Equation for energy density
Webwhere is the current density field and is the magnetic vector potential. This is analogous to the electrostatic energy expression 1 2 ∫ ρ ϕ d V {\textstyle {\frac {1}{2}}\int \rho \phi \,\mathrm {d} V} ; note that neither of these static expressions apply in the case of time-varying charge or current distributions. WebWith electromagnetic waves, doubling the E fields and B fields quadruples the energy density u and the energy flux uc. For a plane wave traveling in the direction of the positive x -axis with the phase of the wave chosen so that the wave maximum is at the origin at t = 0 t = 0 , the electric and magnetic fields obey the equations

WebA continuity equation is useful when a flux can be defined. To define flux, first there must be a quantity q which can flow or move, such as mass, energy, electric charge, momentum, number of molecules, etc.Let ρ be the volume density of this quantity, that is, the amount of q per unit volume.. The way that this quantity q is flowing is described by its flux. WebIn scientific equations, energy density is often denoted by U. [6] Energy density is generally expressed in two ways, although the first is more common: Volumetric energy density - how much energy a system …
