Description
A rotating black hole immersed in an external uniform magnetic field acquires an induced electric charge — the Wald charge — through frame-dragging of the surrounding electromagnetic field. In this work we examine the formation of the Wald charge and its impact on the motion of charged particles near magnetized black holes. We combine an analytical treatment of the induced field structure with general-relativistic particle-in-cell simulations to capture the self-consistent plasma response.
