The vector potential of a point magnetic dipole

S. Sautbekov

Abstract

The retarded vector potential of a point magnetic dipole with an arbitrary time dependence undergoing accelerated relativistic motions is derived. A novel expression for the angular distribution of the radiated power of an arbitrary moving magnetic dipole is obtained. In particular, the case of an uniformly accelerated particle with a constant magnetic moment is considered. The resulting equations are verified by showing that the fields reduce to less general forms found in the literature.
