What are Liénard–Wiechert potentials
The Liénard–Wiechert potentials are a set of equations in electrodynamics that describe the electromagnetic fields generated by a moving charged particle. These potentials are a generalization of the electrostatic and magnetostatic potentials, and they account for the motion of charges, including the effects of their velocity and acceleration. They are particularly useful for describing the
