THE DEPLETION AND DIPOLARIZATION OF THE MAGNETIC FLUX TUBES ABOVE AURORAL ARC

Le résumé fourni par la source

The role of the hot magnetospheric particles (protons) in the formation of the electric fields and the field- aligned currents from the ionosphere to the magnetosphere have been studied. It has been shown that the gradient drift of the hot particles in these cases leads to the depletion of the magnetic flux tubes and increasing of the magnetic field in them. The induction electric field invoked of the magnetic field increasing leads to acceleration of the magnetospheric plasma which despite the energy spread begins to move as one unit. These phenomena occur above the auroral arcs and inverted V precipitations . The evaluations of the magnetic flux tube depletion and increasing the magnetic field in it have been made. The velocities of the magnetospheric plasma in the equatorial plane magnetosphere have been calculated at different distances from the Earth.
