Magnetized Kerr Geometry

Abstract

In this paper, we have derived Kerr metric in a magnetic field using null tetrad formalism. It is observed that the dragging effect on a particle moving in the field of a magnetized Kerr object is enhanced by the introduction of the magnetic field in the instant case.  However, magnetized Kerr black hole is not affected by the magnetic field. We have also derived the Sagnac effect in magnetized Kerr metric and have found that Sagnac effect is affected by magnetic field.
