Liénard-Wiechert potentials due to a ‘classically’ spinning point-charge in non-relativistic arbitrary motion

Abstract

Liénard-Wiechert potentials have been derived for a moving and ‘classically’ spinning point-charge; assuming it to be a small rigid charged-sphere in combined non-relativistic translational and rotational motion, and subsequently reducing its dimensions to ‘point-particle’ limit. The paper demonstrates that when the effect of rotation were taken into account, together with causality, expressions for the LW potentials accompany additional correction terms that contain spin angular momentum (or simply the ‘classical-spin’) of the point-charge.
