Jefimenko’s equations – Wikipedia
McDonald, The relation between expressions for time-dependent electromagnetic fields magnetiism by Jefimenko and by Panofsky and PhillipsAmerican Journal of Physics 65 11 Part of a series of articles about Electromagnetism Electricity Magnetism Electrostatics. GriffithsMark E,ectricity. In other words, the left side of each equation is actually “caused” by the right side, unlike the normal differential expressions for Maxwell’s equations where both sides take place simultaneously.
Views Read Edit View history. There is a widespread interpretation of Maxwell’s equations indicating that spatially varying electric and magnetic fields can cause each other to change in time, thus giving rise to a propagating electromagnetic wave  electromagnetism.
Therefore they can be used for moving charges and currents. From Wikipedia, the free encyclopedia. Charge density and current density are creating them both.
In the typical expressions for Maxwell’s electrocity there is no doubt that both sides are equal to each other, but as Jefimenko eleftricity, ” Jefimenko, Solutions of Maxwell’s equations for electric and magnetic fields in arbitrary mediaAmerican Journal of Physics 60 10— As pointed out by McDonald,  Jefimenko’s equations seem to appear first in in the second edition of Panofsky and Phillips’s classic textbook. The electric field is written in a slightly different – but completely equivalent – form.
Covariant formulation Electromagnetic tensor stress—energy tensor Four-current Electromagnetic four-potential. JefimenkoCausality Electromagnetic Induction and Gravitation2nd ed.: Electromagnetic tensor stress—energy tensor. Retrieved from ” https: This page was last edited on 16 Marchat There are similar expressions for D and H.
They are the general solutions to Maxwell’s equations for any arbitrary distribution of charges and currents. In electromagnetismJefimenko’s equations named after Oleg D.
Jefimenko give the electric field and magnetic field due to a distribution of electric charges and electric current in space, that takes into account the propagation e,ectricity retarded time of the fields due to the finite speed of light and relativistic effects. Hence, it is impossible for E and B fields to be “creating” each other.

However, Magnerism equations show an alternative point of view. Therefore, we must conclude that an electromagnetic field is a dual entity always having an electric and a magnetic component simultaneously created by their common sources: Essential features of these equations are easily observed which is that the right hand sides involve “retarded” time which reflects the “causality” of the expressions. JefimenkoElectricity and Magnetism: These equations are the time-dependent generalization of Coulomb’s law and the Biot—Savart law to electrodynamicswhich were originally true only for adn and magnetostatic fields, and steady currents.
