In the typical expressions for Maxwell’s equations there is no doubt that both sides are equal to each other, but as Jefimenko notes, jefimenkp Covariant formulation Electromagnetic tensor stress—energy tensor Four-current Electromagnetic four-potential.

JefimenkoElectricity and Magnetism: However, Jefimenko’s equations show an alternative point of view. There is a widespread interpretation of Maxwell’s equations indicating that spatially amd electric and magnetic fields can cause each other to change in time, thus giving rise to a propagating electromagnetic wave [5] electromagnetism.

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 delay retarded time of the fields due to the finite speed of light and relativistic effects. The electric field is written in a slightly different – but completely equivalent – form.

These equations are the time-dependent generalization of Coulomb’s law and the Biot—Savart law to electrodynamicswhich were jefijenko true only for electrostatic and magnetostatic fields, and steady currents.

Electricity and Magnetism : Oleg D. Jefimenko :

From Wikipedia, the free encyclopedia. They are the general solutions to Maxwell’s equations for any arbitrary distribution of charges and currents.


Therefore, we must conclude that an electromagnetic kagnetism 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.

Therefore they can be used for moving charges and currents. Charge density and current density are creating them both.

Jefimenko’s equations

As pointed out by McDonald, [8] Jefimenko’s equations seem to appear first in in the second edition of Panofsky and Phillips’s classic textbook. In other words, the left side of each equation is actually “caused” by the right leectricity, unlike the normal differential expressions for Maxwell’s equations where both sides take place simultaneously.

There are similar expressions for D and H. Hence, it is impossible for E and B fields to be “creating” each other.
