THE CONDITIONS FOR THE EXISTENCE OF THE ELECTRIC-FIELD OPPOSITE TO THE CURRENT ALONG THE MAGNETIC-FIELD LINES IN THE THIN PLASMA

The flow of the current along the magnetic field lines in the thin pla sma directed opposite to the electric field is considered. The particl es moving to the equatorial plane are supposed to have mirror points a bove the region of absorption (the ionosphere) and the particles movin g to the ionosphere are supposed to have mirror points below the regio n of absorption. The current, therefore, flows. The functions of the d istribution of the electrons and ions are considered to be mono-energe tic. The energies of the electrons and the ions and their densities on the boundary of absorption are estimated for the potential difference and for the current density which are typical for the auroral field l ines.
