Dynamic equilibrium plasma configurations and physics of the magnetosphere

The impossibility is demonstrated of the limiting transition to a fluid at rest within an area, limited by a specific tangential discontinuity of the 1st, 2nd, or 3rd kind and described by the equations of ideal magnetic hydrodynamics with isotropic or anisotropic pressure. Within the framework of the concept of dynamic equilibrium plasma configuration, evaluations are obtained for the thicknesses of the layer of return flow, electrical field of convection in the magnetosphere and the jump of magnetic field at the magnetopause.
