EFFECT OF ELECTRON VORTICAL MOTION ON THE ION DYNAMICS IN HALL PLASMAS

The dynamics of a Hall plasma is considered under the conditions when the equalization of the Lagrange invariant I = Omega/n (where Omega is the vorticity due to the magnetic field B, which is transverse to the direction of the plasma motion; and n is the plasma density) over the plasma is caused by rapid oscillations. An equation for the ion motio n with allowance for the electron rotational motion is obtained. The d iscontinuous solutions are studied for the scales equal to the collisi onless skin depth c/omega(pc).
