Abstract

Using the Grad-Shafranov equation, we consider a new analytical model of the black hole magnetosphere based on the assumption that the magnetic field is radial near the horizon and uniform (cylindrical) in the jet region. Within this model, we have managed to show that the angular velocity of particles ΩF near the rotation axis of the black hole can be smaller than ΩH/2. This result is consistent with the latest numerical simulations.
