Validity of Blandford-Znajek for description of energy loss of rotating black hole.


The application of Grad-Shafranov equation for BH magnitosphere will be discussed. For slow roation and quasimonopole magnetic field can be constructed exact solution of the problem. Number of boundary conditions of the surface where particles creation tale place and smooth conditions is high enough to determine not only lengthwise current in magnetosphere, but angular velocity of plasma also. As the result the energy losses in Blanfor-Znajek mechanism defines by physical parameters in area of particle creation, but not on the horizon, which is not kazual connected with outer areas of magnetosphere.
