The model facilitates better understanding of magnetic and electric fields in astrophysical objects.
Abstract
Stationary axisymmetric metric describing the exterior field of a rotating, charged sphere endowed with magnetic dipole moment is presented and discussed. It has a remarkably simple multipole structure defined by only four nonzero Hoenselaers-Perj\'es relativistic moments.
