        | A mechanism for the transformation of a
magnetoacoustic wave into an Alfvén wave is proposed. During the compression of
the magnetosphere by the solar wind the inner edge of the plasma sheet and the
contours of B=const move in different ways. In the case of asymmetrical
compression, the contours of B=const will cross the inner edge of the
plasma sheet. To close the drift currents - that flow in the plasma sheet along
the contours of B=const - the appearance of the field-aligned currents is
necessary. This appearance corresponds to the generation of the Alfvén wave. |
