It is shown that, near the event horizon of a rapidly rotating, almost extremal black hole through which an electric current flows, soft photons with trajectories close to spherical orbits can create e/sup +/e/sup -/ pairs. The parameters of spherical orbits of uncharged particles near the horizon in the Kerr-Newman metric are determined. The rotating black hole can approach the extremal state by the inductive accumulation of electric charge when plasma is accreted in the presence of a regular magnetic field. Accreting supermassive black holes can be near the extremal state.
