Abstract
In this work, we study the electromagnetic field structure around rotating (Kerr) black holes. We consider a combination of a uniform magnetic field and a split-monopole field, and work out the total field configuration. The electromagnetic field components are computed from the perspective of Zero-Angular-Momentum Observers (ZAMOs), and we visualize the resulting field lines. Our results show that the relative alignment of the two field components leads to very different topologies. When they point in the same direction, the field lines form open, paraboloidal shapes resembling astrophysical jets. When they point opposite each other, the field lines close into loops, which can set the stage for magnetic reconnection. We also examine the Meissner-like effect in rapidly spinning black holes, and explore how the black hole's charge and external field parameters affect the magnetic flux through the event horizon. Throughout the paper, we work within the test-field approximation, meaning the electromagnetic field is treated as a small perturbation that does not alter the background spacetime geometry.
