In the maagnetism expressions for Maxwell’s equations there is no doubt that both sides are equal to each other, but as Jefimenko notes, ” Covariant formulation Electromagnetic tensor stress—energy tensor Four-current Electromagnetic four-potential. From Wikipedia, the free encyclopedia. However, Jefimenko’s equations show an alternative point of view.
Part of a series of articles aand Electromagnetism Electricity Magnetism Electrostatics. Hence, it is impossible for E and B fields to be “creating” each other. 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.

Charge density and current density are creating them both. Views Read Edit View history. McDonald, The relation between expressions for time-dependent electromagnetic fields given by Jefimenko and by Panofsky and PhillipsAmerican Journal of Physics 65 11 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.

E,ectricity 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.
JefimenkoCausality Electromagnetic Induction and Gravitation2nd ed.: The electric field is written in a slightly different – but completely equivalent – form.
Therefore, we must conclude that an electromagnetic field is a dual entity always having electicity electric and a magnetic component simultaneously created by their common sources: They are the general solutions to Maxwell’s equations for any arbitrary distribution of charges and currents. There are similar expressions for D and H.

Therefore they can be used for moving charges and currents. GriffithsMark A.

Retrieved from ” https: Jefimenko, Solutions of Maxwell’s equations for electric and magnetic fields in arbitrary mediaAmerican Journal of Physics 60 10— 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.
