Jefimenko's equations derivation

Web25 ago 2024 · I'm currently exploring the Jefimenko Equations and practicing using them to find things like the electric field from a particle or the magnetic field around a current. In general, I've read that the Jefimenko Equations are an alternative to the Maxwell Equations. However, one thing that I can't seem to figure out is electromagnetic induction: Web11 dic 2008 · We show how to obtain the first multipole contributions to the electromagnetic radiation emitted by an arbitrary localized source directly from the Jefimenko equation for the magnetic field and the Panofsky-Phillips equation for the electric field. This procedure avoids the unnecessary calculation of the electromagnetic potentials.
