Occhionero, F., 1970: Newtonian electrodynamics from general-relativistic arguments. Astron. Astrophys., 9, 472-474.
In general relativity, a vacuum is electrically polarized in the presence of a magnetic field whenever the mixed components of the metric tensor do not vanish (which occurs in astronomy around a massive rotating object because of the dragging of the inertial frame). This note illustrates the phenomenon by making use of the fact that it does not require curvature and, hence, may occur in a flat space-time: In fact, in corotating coordinates the vacuum around a rotating, magnetic, newtonian star is electrically charged. By assuming near sphericity of the star and an external 22-pole poloidal magnetic field, it is easy to evaluate the electrostatic potential, which reflects the existence of the fictitious charge density with a non-harmonic term proportional to (l/r)n Pn+1(cos θ). This note also establishes a convenient formalism for the treatment of the general-relativistic aspects of the same problem.
