In the offered paper the kinetic theory of equilibrium and stability of the nonelectroneutral current sheaths formed at arbitrary values of medium parameters was developed. Equilibrium distribution function of a current sheath (Harris's function) considering anisotropy of temperature of plasma along and across the layers is summarized. The procedure of examination of a current sheath stability with due regard to plasma polarization effect is offered. Tensor of dielectric permeability is calculated and dispersion equation for investigation of possible instability modes of non-electroneutral current sheath is derived. Non-electroneutral equilibrium solution for a current sheath in the magnetospheric tail is derived and its instability is explored. A possible mechanism of magnetic field annihilation in the magnetospheric tail and acceleration of charged particles in the process of magnetospheric substorm development is considered.
