Field of a dipole in charged blackhole electrostatics
Abstract
By using the solution of Adler and Das (1976) for Maxwell's equations in a ReissnerNordstrom optimally charged background metric, the field of a static electric dipole is found and then, by a duality rotation, the field of a static magnetic dipole is found. A generalization of the concept of electricdipole moment is proposed for static dipoles in curved manifolds, and the behaviour of the fields both for the dipole very near and very far from the singular surface of the ReissnerNordstrom geometry is studied.
