Deduce four maxwell equations in free space
WebMaxwell's equations (covariant formulation) where the partial derivatives may be written in various ways, see 4-gradient. The first equation listed above corresponds to both Gauss's Law (for β = 0) and the Ampère-Maxwell Law (for β = 1, 2, 3). Webboth described by Maxwell’s equations or electromagnetic theory. To see this, we consider the rst two Maxwell’s equations for time-varying elds in vacuum or a source-free medium.3 They are r E = 0 @H @t (3.2.1) r H = "0 @E @t (3.2.2) 2It is to be noted that we will use MKS unit in this course. Another possible unit is the CGS unit used in

WebMathematically, each physical law can be expressed with respect to the coordinates given by an inertial frame of reference by a mathematical equation (for instance, a differential equation) which relates the various coordinates of the various objects in the spacetime. A typical example is Maxwell's equations. Another is Newton's first law. 1.
