{{electromagnetism|cTopic=Covariant formulation}}
{{main|Mathematical descriptions of the electromagnetic field}}
The '''[[covariance and contravariance of vectors|covariant]] formulation of [[classical electromagnetism]]''' refers to ways of writing the laws of classical electromagnetism (in particular, [[Maxwell's equations]] and the [[Lorentz force]]) in a form that is manifestly invariant under [[Lorentz transformation]]s, in the formalism of [[special relativity]] using rectilinear [[inertial frame|inertial coordinate system]]s. These expressions both make it simple to prove that the laws of classical electromagnetism take the same form in any inertial coordinate system, and also provide a way to translate the fields and forces from one frame to another. However, this is not as general as [[Maxwell's equations in curved spacetime]] or non-rectilinear coordinate systems.
 
This article uses [[SI units]] for the purely spatial components of tensors (including vectors), the [[classical treatment of tensors]] and the [[Einstein summation convention]] throughout, and the [[Minkowski metric]] has the form diag (+1, −1, −1, −1). Where the equations are specified as holding in a vacuum, one could instead regard them as the formulation of Maxwell's equations in terms of ''total'' charge and current.
 
For a more general overview of the relationships between classical electromagnetism and special relativity, including various conceptual implications of this picture, see [[Classical electromagnetism and special relativity]].
 
==Covariant objects==
 
===Preliminary 4-vectors===
{{Main|Lorentz covariance}}
For background purposes, we present here three other relevant four-vectors, which are not directly connected to electromagnetism, but which will be useful in this article:
*In [[meter]], the "position" or "coordinate" four-vector is
::<math>x^\alpha = (ct, x, y, z) \,.</math>
*In [[meter]]·[[second]]<sup>−1</sup>, the [[velocity four-vector]] (or [[four-velocity]]) is
::<math>u^\alpha = \gamma(c,\bold{u}) \,</math>
:where γ('''u''') is the [[Lorentz factor]] at the 3-velocity '''u'''.
*In [[kilogram]]·[[meter]]·[[second]]<sup>−1</sup>, the [[four-momentum]] (or [[momentum four-vector]]) of a particle is
::<math>p_\alpha = ( E/c, - \bold{p}) = mu_{\alpha} \,</math>
:where '''p''' is the 3-momentum, ''E'' is the [[kinetic energy|energy]], and ''m'' is the particle's [[rest mass]].
*In [[meter]]<sup>−1</sup> the [[four-gradient]] is
:<math>\partial^{\nu} = \frac{\partial}{\partial x_{\nu}} = \left( \frac{1}{c} \frac{\partial}{\partial t}, - \bold{\nabla} \right) \,,</math>
*In [[meter]]<sup>−2</sup> the [[d'Alembertian]] operator is denoted: <math> \Box </math>.
 
The signs in the following tensor analysis depend on the [[sign convention#Metric signature|convention]] used for the [[metric tensor]]. The convention used here is <tt>+---</tt>, corresponding to the [[Minkowski space#Standard basis|Minkowski metric tensor]]:
:<math>\eta^{\mu \nu}=\begin{pmatrix} 1 & 0 & 0 & 0 \\ 0 & -1 & 0 & 0 \\ 0 & 0 & -1 & 0 \\ 0 & 0 & 0 & -1 \end{pmatrix}\,</math>
 
===Electromagnetic tensor===
{{Main|Electromagnetic tensor}}
The electromagnetic tensor is the combination of the electric and magnetic fields into a covariant [[antisymmetric tensor]]. In [[volt]]·[[second]]s·[[meter]]<sup>−2</sup>, the field strength tensor is written in terms of fields as:<ref name=Vanderlinde>{{Citation

:<math>F_{\alpha \beta} = \left( \begin{matrix}

and the result of raising its indices is

E_y/c  & B_z & 0 & -B_x \\
E_z/c & -B_y & B_x & 0
\end{matrix} \right)\,.</math>
 
where '''E''' is the [[electric field]], '''B''' the [[magnetic field]], and ''c'' the [[speed of light]].
 
===Four-current===
{{Main|Four-current}}
The four-current is the contravariant four-vector which combines [[electric current density]] '''J''' and [[electric charge density]] ρ. In [[ampere]]s·[[meter]]<sup>−2</sup>, it is given by
 
:<math>J^{\alpha}  = \,  (c \rho, \bold{J} ) \,</math>
 
===Four-potential===
{{Main|Four-potential}}
In [[volt]]·[[second]]s·[[meter]]<sup>−1</sup>, the electromagnetic four-potential is a covariant four-vector containing the [[electric potential]] (also called the [[scalar potential]]) φ and [[magnetic vector potential]] (or [[vector potential]]) '''A''', as follows:
:<math>A_{\alpha} = \left(\phi/c, - \bold{A} \right)\,</math>
 
The relation between the electromagnetic potentials and the electromagnetic fields is given by the following equation:
:<math>F_{\alpha \beta} = \partial_{\alpha} A_{\beta} - \partial_{\beta} A_{\alpha} \,</math>
 
===Electromagnetic stress-energy tensor===
{{Main|Electromagnetic stress-energy tensor}}
The electromagnetic stress-energy tensor can be interpreted as the flux (density) of the momentum 4-vector, and is a contravariant symmetric tensor which is the contribution of the electromagnetic fields to the overall [[stress-energy tensor]]. In [[joule]]·[[meter]]<sup>−3</sup>, it is given by
:<math>T^{\alpha\beta} = \begin{pmatrix} \epsilon_{0}E^2/2 + B^2/2\mu_{0} & S_x/c & S_y/c & S_z/c \\ S_x/c & -\sigma_{xx} & -\sigma_{xy} & -\sigma_{xz} \\
S_y/c & -\sigma_{yx} & -\sigma_{yy} & -\sigma_{yz} \\
S_z/c & -\sigma_{zx} & -\sigma_{zy} & -\sigma_{zz} \end{pmatrix}\,</math>
 
where ε<sub>0</sub> is the [[electric constant|electric permittivity of vacuum]], μ<sub>0</sub> is the [[magnetic constant|magnetic permeability of vacuum]], the [[Poynting vector]] in [[watt]]·[[meter]]<sup>−2</sup> is
 
:<math>\bold{S} = \frac{1}{\mu_{0}} \bold{E} \times \bold{B} </math>
 
and the [[Maxwell stress tensor]] in [[joule]]·[[meter]]<sup>−3</sup> is given by
 
:<math>\sigma_{ij} = \epsilon_{0}E_{i}E_{j} + \frac{1}{\mu_{0}}B_{i}B_{j} -
\left(\frac12\epsilon_{0}E^2 + \frac{1}{2\mu_{0}}B^2\right)\delta_{ij} \,.</math>
 
The electromagnetic field tensor ''F'' constructs the electromagnetic stress-energy tensor ''T'' by the equation:
:<math>T^{\alpha\beta} = \frac{1}{\mu_{0}} \left( \eta_{\gamma \nu}F^{\alpha \gamma}F^{\nu \beta} - \frac{1}{4}\eta^{\alpha\beta}F_{\gamma \nu}F^{\gamma \nu}\right)</math>
where η is the [[Minkowski metric]] tensor. Notice that we use the fact that
:<math>\epsilon_{0} \mu_{0} c^2 = 1\,</math>
which is predicted by Maxwell's equations.
 
== Maxwell's equations in vacuum ==
{{Main|Maxwell's equations}}
In a vacuum (or for the microscopic equations, not including macroscopic material descriptions) Maxwell's equations can be written as two tensor equations.
 
The two inhomogeneous Maxwell's equations, [[Gauss's Law]] and [[Ampère's circuital law|Ampère's law]] (with Maxwell's correction) combine into (with +--- metric):<ref>Classical Electrodynamics by Jackson, 3rd Edition, Chapter 11 Special Theory of Relativity</ref>
 
{{Equation box 1
|indent=:
|title='''[[Gauss's Law|Gauss]]-[[Ampère's circuital law|Ampère]] law''' ''(vacuum)''
|equation=<math>\partial_{\alpha}F^{\alpha\beta} = \mu_{0} J^{\beta} </math>
|cellpadding
|border
|border colour = #50C878
|background colour = #ECFCF4}}
 
while the homogeneous equations - [[Faraday's law of induction]] and [[Gauss's law for magnetism]] combine to form:
 
{{Equation box 1
|indent=:
|title='''[[Gauss's law for magnetism|Gauss]]-[[Faraday's law of induction|Faraday]] law''' ''(vacuum)''
|equation=<math>\partial_{\alpha}(\tfrac{1}{2}\epsilon^{\alpha\beta\gamma\delta}F_{\gamma\delta}) = 0 </math>
|cellpadding
|border
|border colour = #50C878
|background colour = #ECFCF4}}
 
where ''F''<sup>αβ</sup> is the [[electromagnetic tensor]], ''J''<sup>α</sup> is the [[4-current]], ε<sup>αβγδ</sup> is the [[Levi-Civita symbol]], and the indices behave according to the [[Einstein summation convention]].
 
The first tensor equation corresponds to four scalar equations, one for each value of β. The second tensor equation actually corresponds to 4<sup>3</sup> = 64 different scalar equations, but only four of these are independent. Using the antisymmetry of the electromagnetic field one can either reduce to an identity (0 = 0) or render redundant all the equations except for those with λ, μ, ν = either 1,2,3 or 2,3,0 or 3,0,1 or 0,1,2.
 
Using the [[antisymmetric tensor]] notation and comma notation for the partial derivative (see [[Ricci calculus]]), the second equation can also be written more compactly as:
 
:<math> F_{[\alpha \beta , \gamma]} =0 </math>
 
In the absence of sources, Maxwell's equations reduce to:
 
:<math>\partial^{\nu} \partial_{\nu}  F^{\alpha\beta} \,\ \stackrel{\mathrm{def}}{=}\ \, \Box F^{\alpha\beta} \,\ \stackrel{\mathrm{def}}{=}\ {1 \over c^2 } { \partial^2 F^{\alpha\beta} \over {\partial t }^2  } - \nabla^2 F^{\alpha\beta}= 0 \,,</math>
 
which is an [[electromagnetic wave equation]] in the field strength tensor.
 
===Maxwell's equations in the Lorenz gauge===
<!--Lorenz is the correct name (not Lorentz). Ludvig Lorenz ≠ Hendrik Lorentz -->
{{Main|Lorenz gauge condition}}
 
The [[Lorenz gauge condition]] is a Lorentz-invariant gauge condition. (This can be contrasted with other [[gauge fixing|gauge conditions]] such as the [[Coulomb gauge]]; if it holds in one [[inertial frame]] it will generally not hold in any other.) It is expressed in terms of the four-potential as follows:
 
:<math>\partial_{\alpha} A^{\alpha} = \partial^{\alpha} A_{\alpha}=0 \,.</math>
 
In the Lorenz gauge, the microscopic Maxwell's equations can be written as:
 
:<math>\Box A^{\sigma} = \mu_{0} \, J^{\sigma}\,</math>
 
==Lorentz force==
 
{{Main|Lorentz force}}
 
===Charged particle===
[[File:Lorentz force particle.svg|200px|thumb|[[Lorentz force]] '''f''' on a [[charged particle]] (of [[electric charge|charge]] ''q'') in motion (instantaneous velocity '''v'''). The [[electric field|'''E''' field]] and [[magnetic field|'''B''' field]] vary in space and time.]]
 
Electromagnetic (EM) fields affect the motion of [[electric charge|electrically charged]] matter: due to the [[Lorentz force]]. In this way, EM fields can be [[Particle detector|detected]] (with applications in [[particle physics]], and natural occurrences such as in [[Aurora (astronomy)|aurorae]]). In relativistic form, the Lorentz force (in [[Newton (unit)|newton]]s) uses the field strength tensor as follows.<ref>The assumption is made that no forces other than those originating in '''E''' and '''B''' are present, that is, no [[gravitation]]al, [[weak force|weak]] or [[strong force|strong]] forces.</ref>
 
Expressed in terms of [[coordinate time]] (not proper time) ''t'' in [[second]]s, it is:
:<math> { d p_{\alpha} \over { d t } } =  q \, F_{\alpha \beta} \, \frac{d x^\beta}{d t} \,</math>
 
where ''p''<sub>α</sub> is the [[four-momentum]] (see above), ''q'' is the [[Electric charge|charge]] (in [[coloumb]]s), and ''x''<sup>β</sup> is the position in [[meter]]s.
 
In the co-moving reference frame, this yields the so-called 4-force
 
:<math> \frac{d p_{\alpha}}{d \tau} \, = q \, F_{\alpha \beta} \, u^\beta </math>
 
where ''u''<sup>β</sup> is the [[four-velocity]] (see above), and τ is the particle's [[proper time]] which is related to coordinate time by ''dt'' = γ''d''τ.
 
===Charge continuum===
[[File:Lorentz force continuum.svg|200px|thumb|Lorentz force (per unit 3-volume) '''f''' on a continuous [[charge distribution]] ([[charge density]] ρ) in motion. The 3-[[current density]] '''J''' corresponds to the motion of the charge element ''dq'' in [[volume element]] ''dV'' and varies throughout the continuum.]]
 
{{see also|continuum mechanics}}
In a continuous medium, the 3D ''density of force'' combines with the ''density of power'' to form a covariant 4-vector, ''f''<sub>μ</sub>. The spatial part is the result of dividing the force on a small cell (in 3-space) by the volume of that cell. The time component is 1/''c'' times the power transferred to that cell divided by the volume of the cell. The density of [[Lorentz force]] is the part of the density of force due to electromagnetism. Its spatial part is
:<math> - \bold{f} =  - (\rho \bold{E} + \bold{J} \times \bold{B})\,</math>.
 
In manifestly covariant notation it becomes:
:<math>f_{\alpha} = F_{\alpha\beta}J^{\beta} .\!</math>
 
The relationship between Lorentz force and electromagnetic stress-energy tensor is
:<math>f^{\alpha} = - {T^{\alpha\beta}}_{,\beta} \equiv  - \frac{\partial T^{\alpha\beta}}{\partial x^\beta}.</math>
 
==Conservation laws==
 
===Electric charge===
 
The [[continuity equation]]:
:<math>{J^{\alpha}}_{,\alpha} \, \stackrel{\mathrm{def}}{=} \,  \partial_{\alpha} J^{\alpha} \, = \, 0 \,.</math>
expresses [[charge conservation]].
 
===Electromagnetic energy-momentum===
 
Using the Maxwell equations, one can see that the [[electromagnetic stress-energy tensor]] (defined above) satisfies the following differential equation, relating it to the electromagnetic tensor and the current four-vector
:<math>{T^{\alpha\beta}}_{,\beta} + F^{\alpha\beta} J_{\beta} = 0</math>
 
or
:<math>\eta_{\alpha \nu} { T^{\nu \beta } }_{,\beta} + F_{\alpha \beta} J^{\beta} = 0,</math>
 
which expresses the conservation of linear momentum and energy by electromagnetic interactions.
 
==Covariant objects in matter==
 
===Free and bound 4-currents===
 
In order to solve the equations of electromagnetism given here, it is necessary to add information about how to calculate the electric current, ''J''<sup>ν</sup> Frequently, it is convenient to separate the current into two parts, the free current and the bound current, which are modeled by different equations;
 
:<math>J^{\nu} = {J^{\nu}}_{\text{free}} + {J^{\nu}}_{\text{bound}} \,,</math>
 
where
:<math>{J^{\nu}}_{\text{free}}=(c\rho_{\text{free}},\mathbf{J}_{\text{free}})=\left(c \nabla \cdot \mathbf{D}, - \ \frac{\partial \mathbf{D}}{\partial t}+\nabla\times\mathbf{H}\right) \,,</math>
:<math>{J^{\nu}}_{\text{bound}}=(c\rho_{\text{bound}},\mathbf{J}_{\text{bound}})=\left(- \ c \nabla \cdot \mathbf{P}, \frac{\partial \mathbf{P}}{\partial t}+\nabla\times\mathbf{M}\right) \,.</math>
 
[[Maxwell's equations#Maxwell's "macroscopic" equations|Maxwell's macroscopic equations]] have been used, in addition the definitions of the [[electric displacement]] '''D''' (in [[coloumb]]·[[meter]]<sup>−1</sup>) and the [[magnetic field|magnetic intensity]] '''H''' (in [[ampere]]·[[meter]]<sup>−1</sup>):
 
:<math>\bold{D} = \epsilon_0 \bold{E} + \bold{P} \,</math>
:<math>\bold{H} = \frac{1}{\mu_{0}} \bold{B} - \bold{M} \,.</math>
 
where '''M''' is the [[magnetization]] (in [[ampere]]·[[meter]]<sup>−2</sup>) and '''P''' the [[electric polarization]] (in [[coulomb]]·[[meter]]<sup>−2</sup>).
 
===Magnetization-polarization tensor===
 
The bound current is derived from the '''P''' and '''M''' fields which form an antisymmetric contravariant magnetization-polarization tensor (in [[ampere]]·[[meter]]<sup>2</sup>)<ref name=Vanderlinde />
:<math>
  \mathcal{M}^{\mu \nu} =
  \begin{pmatrix}
  0    & P_xc & P_yc & P_zc \\
  - P_xc & 0      &  - M_z  & M_y    \\
  -  P_yc & M_z    & 0      & - M_x  \\
  -  P_zc & - M_y  & M_x    & 0     
  \end{pmatrix},
</math>
 
which determines the bound current
:<math>{J^{\nu}}_{\text{bound}}=\partial_{\mu} \mathcal{M}^{\mu \nu} \,.</math>
 
===Electric displacement tensor===
 
If this is combined with ''F''<sup>μν</sup> we get the antisymmetric contravariant  electromagnetic displacement tensor (in [[ampere]]·[[meter]]<sup>−1</sup>) which combines the '''D''' and '''H''' fields as follows:
:<math>
  \mathcal{D}^{\mu \nu} =
  \begin{pmatrix}
  0    & - D_xc & - D_yc & - D_zc \\
  D_xc & 0      & - H_z  & H_y    \\
  D_yc & H_z    & 0      & - H_x  \\
  D_zc & - H_y  & H_x    & 0     
  \end{pmatrix}.
</math>
 
The three field tensors are related by:
 
:<math>\mathcal{D}^{\mu \nu} = \frac{1}{\mu_{0}} F^{\mu \nu} - \mathcal{M}^{\mu \nu} \,</math>
 
which is equivalent to the definitions of the '''D''' and '''H''' fields given above.
 
==Maxwell's equations in matter==
 
The result is that [[Ampère's circuital law|Ampère's law]],
:<math>\bold{\nabla} \times \bold{H} = \bold{J}_{\text{free}} + \frac{\partial \bold{D}} {\partial t}</math>,
and [[Gauss's law]],
:<math>\bold{\nabla} \cdot \bold{D} = \rho_{\text{free}}</math>,
 
combine into one equation:
 
{{Equation box 1
|indent=:
|title='''[[Gauss's Law|Gauss]]-[[Ampère's circuital law|Ampère]] law''' ''(matter)''
|equation=<math>{J^{\nu}}_{\text{free}} = \partial_{\mu} \mathcal{D}^{\mu \nu} </math>
|cellpadding
|border
|border colour = #0073CF
|background colour=#F5FFFA}}
 
The bound current and free current as defined above are automatically and separately conserved
:<math>\partial_{\nu} {J^{\nu}}_{\text{bound}} = 0 \,</math>
:<math>\partial_{\nu} {J^{\nu}}_{\text{free}} = 0 \,.</math>
 
===Constitutive equations===
 
{{main|Constitutive equation}}
 
====Vacuum====
 
In a vacuum, the constitutive relations between the field tensor and displacement tensor are:
 
:<math>\mu_0 \mathcal{D}^{\mu \nu} = \eta^{\mu \alpha} F_{\alpha \beta} \eta^{\beta \nu} \,.</math>
 
Antisymmetry reduces these 16 equations to just six independent equations. Because it is usual to define ''F''<sup>μν</sup> by
:<math>F^{\mu \nu} = \eta^{\mu \alpha} F_{\alpha \beta} \eta^{\beta \nu} \,</math>
 
the constitutive equations may, in a ''vacuum'', be combined with Gauss-Ampère law to get:
:<math>\partial_\beta F^{\alpha \beta} = \mu_0 J^{\alpha}. \!</math>
 
The electromagnetic stress-energy tensor in terms of the displacement is:
 
:<math>T_\alpha^\pi = F_{\alpha\beta} \mathcal{D}^{\pi\beta} - \frac{1}{4} \delta_\alpha^\pi F_{\mu\nu} \mathcal{D}^{\mu\nu}</math>
 
where δ<sub>α</sub><sup>π</sup> is the [[Kronecker delta]]. When the upper index is lowered with η, it becomes symmetric and is part of the source of the gravitational field.
 
====Matter====
 
Thus we have reduced the problem of modeling the current, ''J''<sup>ν</sup> to two (hopefully) easier problems &mdash; modeling the free current, ''J''<sup>ν</sup><sub>free</sub> and modeling the magnetization and polarization, <math> \mathcal{M}^{\mu\nu}</math>. For example, in the simplest materials at low frequencies, one has
:<math>\bold{J}_{\text{free}} = \sigma \bold{E} \,</math>
:<math>\bold{P} = \epsilon_0 \chi_e \bold{E} \,</math>
:<math>\bold{M} = \chi_m \bold{H} \,</math>
 
where one is in the instantaneously comoving inertial frame of the material, σ is its [[electrical conductivity]], χ<sub>e</sub> is its [[electric susceptibility]], and χ<sub>m</sub> is its [[magnetic susceptibility]].
 
The constitutive relations between the <math>\mathcal{D}</math> and ''F'' tensors, proposed by [[Hermann Minkowski|Minkowski]] for a linear materials (that is, '''E''' is [[Proportionality (mathematics)|proportional]] to '''D''' and '''B''' proportional to '''H'''), are:<ref>{{cite book|title=Introduction to Electrodynamics|edition=3rd|author=D.J. Griffiths|publisher = Dorling Kindersley|year=2007|page=563|isbn=81-7758-293-3}}</ref>
 
:<math>\mathcal{D}^{\mu\nu}u_\nu= c^2\epsilon F^{\mu\nu} u_\nu</math>
:<math>{\star\mathcal{D}^{\mu\nu}}u_\nu= \frac{1}{\mu}{\star F^{\mu\nu}} u_\nu</math>
 
where ''u'' is the 4-velocity of material, ε and μ are respectively the proper [[permittivity]] and [[Permeability (electromagnetism)|permeability]] of the material (i.e. in rest frame of material), <math>\star</math> and denotes the [[Hodge dual]].
 
==Lagrangian for classical electrodynamics==
 
===Vacuum===
The [[Lagrangian]] (Lagrangian density) for classical electrodynamics (in [[joule]]·[[meter]]<sup>−3</sup>) is
:<math> \mathcal{L} \, = \, \mathcal{L}_{\mathrm{field}} + \mathcal{L}_{\mathrm{int}} = - \frac{1}{4 \mu_0} F^{\alpha \beta} F_{\alpha \beta} - A_{\alpha} J^{\alpha} \,.</math>
 
In the interaction term, the four-current should be understood as an abbreviation of many terms expressing the electric currents of other charged fields in terms of their variables; the four-current is not itself a fundamental field.
 
The [[Euler-Lagrange equation]] for the electromagnetic Lagrangian density <math> \mathcal{L}(A_{\alpha},\partial_{\beta}A_{\alpha})\,</math> can be stated as follows:
:<math> \partial_{\beta}\left[\frac{\partial \mathcal{L}}{\partial (\partial_{\beta}A_{\alpha})}\right]  - \frac{\partial \mathcal{L}}{\partial A_{\alpha}}=0 \,.</math>
 
Noting
:<math>F_{\mu \nu}=\partial_{\mu} A_{\nu} - \partial_{\nu} A_{\mu}\,</math>,
the expression inside the square bracket is
:<math>\begin{align}\frac{\partial \mathcal{L}}{\partial (\partial_{\beta}A_{\alpha})} & = - \ \frac{1}{4 \mu_0}\ \frac{\partial (F_{\mu \nu}\eta^{\mu\lambda}\eta^{\nu\sigma}F_{\lambda \sigma})}{\partial (\partial_{\beta}A_{\alpha})} \\
& = - \ \frac{1}{4 \mu_0}\ \eta^{\mu\lambda}\eta^{\nu\sigma}
\left(F_{\lambda\sigma}(\delta^{\beta}_{\mu}\delta^{\alpha}_{\nu} - \delta^{\beta}_{\nu}\delta^{\alpha}_{\mu})
+F_{\mu\nu}(\delta^{\beta}_{\lambda}\delta^{\alpha}_{\sigma} - \delta^{\beta}_{\sigma}\delta^{\alpha}_{\lambda})
\right) \\
& = - \ \frac{F^{\beta\alpha}}{\mu_0}\,.
\end{align}</math>
 
The second term is
:<math>\frac{\partial \mathcal{L}}{\partial A_{\alpha}}= - J^{\alpha} \,.</math>
 
Therefore, the electromagnetic field's equations of motion are
:<math> \frac{\partial F^{\beta\alpha}}{\partial x^{\beta}}=\mu_0 J^{\alpha} \,.</math>
which is one of the Maxwell equations above.
 
===Matter===
 
Separating the free currents from the bound currents, another way to write the Lagrangian density is as follows:
:<math> \mathcal{L} \, = \, - \frac{1}{4 \mu_0} F^{\alpha \beta} F_{\alpha \beta} - A_{\alpha} J^{\alpha}_{\text{free}} + \frac12 F_{\alpha \beta} \mathcal{M}^{\alpha \beta} \,.</math>
 
Using Euler-Lagrange equation, the equations of motion for <math> \mathcal{D}^{\mu\nu}</math> can be derived.
 
The equivalent expression in non-relativistic vector notation is
:<math> \mathcal{L} \, = \, \frac12 \left(\epsilon_{0} E^2 - \frac{1}{\mu_{0}} B^2\right) - \phi \, \rho_{\text{free}} + \bold{A} \cdot \bold{J}_{\text{free}} + \bold{E} \cdot \bold{P} + \bold{B} \cdot \bold{M} \,.</math>

Earlier than you determine whether or not stainless steel cookware is value shopping for, lets first talk about what stainless steel cookware is. Chrome steel is made from an alloy, or a mix of metals. Mostly, fundamental iron with chromium, nickel or some other minor metals. The chromium supplies rust protection and provides your cookware sturdiness. The nickel provides rust safety as effectively, and provides a refined look. Most effectively made chrome steel cookware has copper or aluminum added to the underside of the pan or pot. This is finished to increases the ability of the pot or pan to conduct heat.
One of the best stainless-steel cookware is the principle category, however nonetheless it is divided into several subcategories based mostly on the quality and the price range. It may be confusing to decide on the very best stainless-steel cookware out of the categories that may meet your requirements. That is where we took a step forward to explain you all the knowledge that will likely be helpful so that you can understand how to decide on the best chrome steel cookware. The best stainless-steel cookware set is manufactured from low-cost to expensive and quality constructed pots and pans.
You will find magnetic stainless steel within the layer on the outside of some high quality pieces of stainless-steel. That is to make it compatible with induction stovetops, which involve using a rapidly charging electromagnetic subject to warmth cookware. High-high quality stainless steel, like All-Clad , uses three layers of steel—the austenite layer of metal on the within, ferrite steel on the outside, and a layer of aluminum sandwiched between the two for optimum heat conductivity (metal alone doesn't conduct warmth evenly). Lesser-high quality stainless-steel is usually only one layer of austenitic chrome steel.
Aesthetically talking, chrome steel is a wise alternative when you favor to show or hang pots or pans. The clean, crisp look of all chrome steel kitchenware can remodel a mishmash of cookware into a complicated décor statement. Chrome steel kettles, such because the Cuisinart Tea Kettle will combine individual kitchenware right into a cohesive and nice entity. Take into account buying stainless-steel utensils as well. Already acquired a gorgeous stainless steel cookware assortment? The Cuisinart Chef’s Collection stainless pot rack could be the crowning glory for a kitchen, liberating up space and making these pots and pans readily accessible. Get the stainless-steel cookware of your culinary goals at Macy’s!
Arduous-anodized aluminum cookware is among the most popular forms of material, despite the fact that many people do not fairly perceive the development. Hard-anodized aluminum is plain aluminum that has been processed in a series of chemical baths charged with an electrical present. The result's a fabric that has the same superior warmth conductivity as aluminum however is non-reactive with acidic meals, similar to tomatoes, and twice as hard as chrome steel. Two drawbacks to laborious-anodized cookware are that it's not dishwasher-secure and, because it isn't magnetic, it will not work with induction range tops.
The enamel over metal method creates a piece that has the heat distribution of carbon steel and a non-reactive, low-stick surface. In the event you loved this information and you desire to acquire details about best stainless steel cookware i implore you to pay a visit to our page. Such pots are a lot lighter than most different pots of comparable dimension, are cheaper to make than chrome steel pots, and would not have the rust and reactivity problems with forged iron or carbon steel. quotation needed Enamel over metal is right for large stockpots and for different giant pans used mostly for water-primarily based cooking. Because of its mild weight and simple cleanup, enamel over metal can also be standard for cookware used while tenting. Clad aluminium or copper edit
Unique specialty cookware items served a la carte to compliment any cookware set are constructed of a sturdy Stainless Steel with a brushed exterior finish. Designed with an impression bonded, aluminum disk encapsulated base which distributes warmth quickly and evenly to permit exact temperature management. Handles are riveted for durability and efficiency. The New Specialty Cookware is compatible for all vary sorts together with induction. Along with the multi use function, another unique characteristic is bottom to top interior quantity markings in each quarts and metric measurement; and each bit comes with a tempered glass lid, oven safe to 350°F.
Whether or not you are a cooking enthusiasts, knowledgeable chef or simply cooking for your family you know the importance of getting a totally stocked kitchen. Not solely do you want the fitting elements, but you also need the right instruments to get the job performed. In any sort of fundamental cooking coaching lesson, you will be taught that chrome steel is your new finest pal when it comes to kitchen cookware. What additionally, you will study is that quality cooking tools does not normally come at a reduced price. Because of this, you will need to take good care of your cookware! Listed here are some fundamentals for stainless steel care.
To combat the uneven heating downside, most stainless steel pans are laminations of aluminum or copper on the underside to spread the warmth around, and stainless-steel contained in the pan to provide a cooking floor that's impervious to whatever you might put inside. In my experience, this chrome steel floor continues to be too sticky to fry on, and when you ever burn it you get a permanent hassle spot. But, sometimes a stainless-steel cooking surface turns out to be useful when you can't use aluminum (see below) so I keep some round. Choose one thing with a fairly thick aluminum layer on the underside.
Well, until you’re a metals professional and go examine the factory where the steel is made to see whether or not their manufacturing course of creates a pure austenite without corrosive supplies shaped, you’re not going to know for sure whether or not the craftsmanship of your stainless is of the very best quality. I think your greatest wager is to simply buy high-quality chrome steel from the start, from a brand with a reputation for good quality. But, I believe I have found out one way that you would be able to decide if the stainless cookware you already have is probably reactive.

Recently had a family visit to Urnes Stave Church. The covariant formulation of classical electromagnetism refers to ways of writing the laws of classical electromagnetism (in particular, Maxwell's equations and the Lorentz force) in a form that is manifestly invariant under Lorentz transformations, in the formalism of special relativity using rectilinear inertial coordinate systems. These expressions both make it simple to prove that the laws of classical electromagnetism take the same form in any inertial coordinate system, and also provide a way to translate the fields and forces from one frame to another. However, this is not as general as Maxwell's equations in curved spacetime or non-rectilinear coordinate systems.

This article uses SI units for the purely spatial components of tensors (including vectors), the classical treatment of tensors and the Einstein summation convention throughout, and the Minkowski metric has the form diag (+1, −1, −1, −1). Where the equations are specified as holding in a vacuum, one could instead regard them as the formulation of Maxwell's equations in terms of total charge and current.

For a more general overview of the relationships between classical electromagnetism and special relativity, including various conceptual implications of this picture, see Classical electromagnetism and special relativity.

Recently had a family visit to Urnes Stave Church. In a vacuum (or for the microscopic equations, not including macroscopic material descriptions) Maxwell's equations can be written as two tensor equations.

The two inhomogeneous Maxwell's equations, Gauss's Law and Ampère's law (with Maxwell's correction) combine into (with +--- metric):[2]

The Aharonov–Casher effect is a quantum mechanical phenomenon in which a traveling magnetic dipole is affected by an electric field. It is dual to the Aharonov–Bohm effect, in which the quantum phase of a charged particle depends upon which side of a magnetic flux tube it comes through. In the Aharonov–Casher effect, the particle has a magnetic moment and the tubes are charged instead. It is used for example to observe interference of neutrons or fluxons.

In both effects the particle acquires some phase shift () while traveling along some path P. In the Aharonov–Bohm effect it is

The Aharonov–Casher effect is a quantum mechanical phenomenon in which a traveling magnetic dipole is affected by an electric field. It is dual to the Aharonov–Bohm effect, in which the quantum phase of a charged particle depends upon which side of a magnetic flux tube it comes through. In the Aharonov–Casher effect, the particle has a magnetic moment and the tubes are charged instead. It is used for example to observe interference of neutrons or fluxons.

In both effects the particle acquires some phase shift () while traveling along some path P. In the Aharonov–Bohm effect it is

where Fαβ is the electromagnetic tensor, Jα is the 4-current, εαβγδ is the Levi-Civita symbol, and the indices behave according to the Einstein summation convention.

The first tensor equation corresponds to four scalar equations, one for each value of β. The second tensor equation actually corresponds to 43 = 64 different scalar equations, but only four of these are independent. Using the antisymmetry of the electromagnetic field one can either reduce to an identity (0 = 0) or render redundant all the equations except for those with λ, μ, ν = either 1,2,3 or 2,3,0 or 3,0,1 or 0,1,2.

Using the antisymmetric tensor notation and comma notation for the partial derivative (see Ricci calculus), the second equation can also be written more compactly as:

In the absence of sources, Maxwell's equations reduce to:

which is an electromagnetic wave equation in the field strength tensor.

Maxwell's equations in the Lorenz gauge

Mining Engineer (Excluding Oil ) Truman from Alma, loves to spend time knotting, largest property developers in singapore developers in singapore and stamp collecting. Recently had a family visit to Urnes Stave Church.

The Lorenz gauge condition is a Lorentz-invariant gauge condition. (This can be contrasted with other gauge conditions such as the Coulomb gauge; if it holds in one inertial frame it will generally not hold in any other.) It is expressed in terms of the four-potential as follows:

In the Lorenz gauge, the microscopic Maxwell's equations can be written as:

Mining Engineer (Excluding Oil ) Truman from Alma, loves to spend time knotting, largest property developers in singapore developers in singapore and stamp collecting. Recently had a family visit to Urnes Stave Church.

Charged particle

Lorentz force f on a charged particle (of charge q) in motion (instantaneous velocity v). The E field and B field vary in space and time.

Electromagnetic (EM) fields affect the motion of electrically charged matter: due to the Lorentz force. In this way, EM fields can be detected (with applications in particle physics, and natural occurrences such as in aurorae). In relativistic form, the Lorentz force (in newtons) uses the field strength tensor as follows.[3]

Expressed in terms of coordinate time (not proper time) t in seconds, it is:

where pα is the four-momentum (see above), q is the charge (in coloumbs), and xβ is the position in meters.

In the co-moving reference frame, this yields the so-called 4-force

where uβ is the four-velocity (see above), and τ is the particle's proper time which is related to coordinate time by dt = γdτ.

Charge continuum

Lorentz force (per unit 3-volume) f on a continuous charge distribution (charge density ρ) in motion. The 3-current density J corresponds to the motion of the charge element dq in volume element dV and varies throughout the continuum.

Singapore has been beckoning to traders ever since the value of properties in Singapore started sky rocketing just a few years again. Many businesses have their places of work in Singapore and prefer to own their own workplace area within the country once they decide to have a everlasting office. Rentals in Singapore in the corporate sector can make sense for some time until a business has discovered a agency footing. Finding Commercial Property Singapore takes a variety of time and effort but might be very rewarding in the long term.

is changing into a rising pattern among Singaporeans as the standard of living is increasing over time and more Singaporeans have abundance of capital to invest on properties.

In 12 months 2013, c ommercial retails, shoebox residences and mass market properties continued to be the celebrities of the property market. Models are snapped up in report time and at document breaking prices. Builders are having fun with overwhelming demand and patrons need more. We feel that these segments of the property market are booming is a repercussion of the property cooling measures no.6 and no. 7. With additional buyer's stamp responsibility imposed on residential properties, buyers change their focus to commercial and industrial properties. I imagine every property purchasers need their property funding to understand in value. In a continuous medium, the 3D density of force combines with the density of power to form a covariant 4-vector, fμ. The spatial part is the result of dividing the force on a small cell (in 3-space) by the volume of that cell. The time component is 1/c times the power transferred to that cell divided by the volume of the cell. The density of Lorentz force is the part of the density of force due to electromagnetism. Its spatial part is

.

In manifestly covariant notation it becomes:

The relationship between Lorentz force and electromagnetic stress-energy tensor is

Conservation laws

Electric charge

The continuity equation:

expresses charge conservation.

Electromagnetic energy-momentum

Using the Maxwell equations, one can see that the electromagnetic stress-energy tensor (defined above) satisfies the following differential equation, relating it to the electromagnetic tensor and the current four-vector

or

which expresses the conservation of linear momentum and energy by electromagnetic interactions.

Covariant objects in matter

Free and bound 4-currents

In order to solve the equations of electromagnetism given here, it is necessary to add information about how to calculate the electric current, Jν Frequently, it is convenient to separate the current into two parts, the free current and the bound current, which are modeled by different equations;

where

Maxwell's macroscopic equations have been used, in addition the definitions of the electric displacement D (in coloumb·meter−1) and the magnetic intensity H (in ampere·meter−1):

where M is the magnetization (in ampere·meter−2) and P the electric polarization (in coulomb·meter−2).

Magnetization-polarization tensor

The bound current is derived from the P and M fields which form an antisymmetric contravariant magnetization-polarization tensor (in ampere·meter2)[1]

which determines the bound current

Electric displacement tensor

If this is combined with Fμν we get the antisymmetric contravariant electromagnetic displacement tensor (in ampere·meter−1) which combines the D and H fields as follows:

The three field tensors are related by:

which is equivalent to the definitions of the D and H fields given above.

Maxwell's equations in matter

The result is that Ampère's law,

,

and Gauss's law,

,

combine into one equation:

The Aharonov–Casher effect is a quantum mechanical phenomenon in which a traveling magnetic dipole is affected by an electric field. It is dual to the Aharonov–Bohm effect, in which the quantum phase of a charged particle depends upon which side of a magnetic flux tube it comes through. In the Aharonov–Casher effect, the particle has a magnetic moment and the tubes are charged instead. It is used for example to observe interference of neutrons or fluxons.

In both effects the particle acquires some phase shift () while traveling along some path P. In the Aharonov–Bohm effect it is

While for the Aharonov–Casher effect it is

where is its charge and is the magnetic moment.

The bound current and free current as defined above are automatically and separately conserved

Constitutive equations

Mining Engineer (Excluding Oil ) Truman from Alma, loves to spend time knotting, largest property developers in singapore developers in singapore and stamp collecting. Recently had a family visit to Urnes Stave Church.

Vacuum

In a vacuum, the constitutive relations between the field tensor and displacement tensor are:

Antisymmetry reduces these 16 equations to just six independent equations. Because it is usual to define Fμν by

the constitutive equations may, in a vacuum, be combined with Gauss-Ampère law to get:

The electromagnetic stress-energy tensor in terms of the displacement is:

where δαπ is the Kronecker delta. When the upper index is lowered with η, it becomes symmetric and is part of the source of the gravitational field.

Matter

Thus we have reduced the problem of modeling the current, Jν to two (hopefully) easier problems — modeling the free current, Jνfree and modeling the magnetization and polarization, . For example, in the simplest materials at low frequencies, one has

where one is in the instantaneously comoving inertial frame of the material, σ is its electrical conductivity, χe is its electric susceptibility, and χm is its magnetic susceptibility.

The constitutive relations between the and F tensors, proposed by Minkowski for a linear materials (that is, E is proportional to D and B proportional to H), are:[4]

where u is the 4-velocity of material, ε and μ are respectively the proper permittivity and permeability of the material (i.e. in rest frame of material), and denotes the Hodge dual.

Lagrangian for classical electrodynamics

Vacuum

The Lagrangian (Lagrangian density) for classical electrodynamics (in joule·meter−3) is

In the interaction term, the four-current should be understood as an abbreviation of many terms expressing the electric currents of other charged fields in terms of their variables; the four-current is not itself a fundamental field.

The Euler-Lagrange equation for the electromagnetic Lagrangian density can be stated as follows:

Noting

,

the expression inside the square bracket is

The second term is

Therefore, the electromagnetic field's equations of motion are

which is one of the Maxwell equations above.

Matter

Separating the free currents from the bound currents, another way to write the Lagrangian density is as follows:

Using Euler-Lagrange equation, the equations of motion for can be derived.

The equivalent expression in non-relativistic vector notation is

That is the place your good religion deposit will likely be taken into account and will kind part or all of your security deposit. Anticipate to have a proportionate amount deducted out of your deposit if something is discovered to be damaged if you move out. It's best to you'll want to test the inventory drawn up by the owner, which can detail all objects in the property and their condition. If you happen to fail to notice any harm not already mentioned within the inventory before transferring in, you danger having to pay for it yourself.

    In case you are in search of an actual estate or Singapore property agent on-line, you simply should belief your intuition. It's because you do not know which agent is nice and which agent will not be. Carry out research on several brokers by looking out the internet. As soon as if you end up positive that a selected agent is dependable and reliable, you can choose to utilize his partnerise in finding you a home in Singapore. Most of the time, a property agent is taken into account to be good if he or she locations the contact data on his website. This may mean that the agent does not mind you calling them and asking them any questions relating to new properties in singapore in Singapore. After chatting with them you too can see them in their office after taking an appointment.

    Have handed an trade examination i.e Widespread Examination for House Brokers (CEHA) or Actual Property Agency (REA) examination, or equal; Exclusive brokers are extra keen to share listing information thus making certain the widest doable coverage inside the real estate community via Multiple Listings and Networking. Accepting a severe provide is simpler since your agent is totally conscious of all advertising activity related with your property. This reduces your having to check with a number of agents for some other offers. Price control is easily achieved.

    Once you place down the one per cent choice price to carry down a non-public property, it's important to accept its situation as it is whenever you move in – faulty air-con, choked rest room and all. Get round this by asking your agent to incorporate a ultimate inspection clause within the possibility-to-buy letter. HDB flat patrons routinely take pleasure in this security net. "There's a ultimate inspection of the property two days before the completion of all HDB transactions. If the air-con is defective, you can request the seller to repair it," says Kelvin.

    15.6.1 As the agent is an intermediary, generally, as soon as the principal and third party are introduced right into a contractual relationship, the agent drops out of the image, subject to any problems with remuneration or indemnification that he could have against the principal, and extra exceptionally, against the third occasion. Generally, agents are entitled to be indemnified for all liabilities reasonably incurred within the execution of the brokers´ authority.

    To achieve the very best outcomes, you must be always updated on market situations, including past transaction information and reliable projections.
