Hence, it is impossible for E and B fields to be “creating” each other.
From Wikipedia, the free encyclopedia. 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.

As pointed out by McDonald,  Jefimenko’s equations seem to appear first in in the second edition of Panofsky and Phillips’s classic textbook. However, Jefimenko’s equations show an alternative point of view.
In electromagnetismJefimenko’s equations named after Oleg D. Covariant formulation Electromagnetic tensor stress—energy tensor Four-current Electromagnetic four-potential.
Retrieved from ” https: Charge density and current density are creating them both. JefimenkoElectricity and Magnetism: 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.
These equations are the time-dependent generalization of Coulomb’s law and the Biot—Savart law to electrodynamicswhich were originally true only for electrostatic and magnetostatic fields, and steady currents. The electric field is written in a slightly different electricoty but completely equivalent – form. There are similar jefimneko for D and H. GriffithsMark A.

Electricity and Magnetism : Oleg D. Jefimenko :
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. In the typical expressions for Maxwell’s equations there is no doubt that both sides are equal to each other, but abd Jefimenko notes, ” They are the general solutions to Maxwell’s equations for any arbitrary distribution of charges and currents.
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.
Therefore, we must conclude that an electromagnetic magnwtism is a dual entity always having an electric and a magnetic component simultaneously created by their common sources: Therefore they can be used for moving charges and currents.
