abstract:
In the present paper we propose that mirror force can be an effective mechanism to sustain a parallel electric field for Alfven waves. In a converging magnetic field, electron's mobility is restricted by the mirror force. Therefore a parallel electric field must exist for field aligned currents carried by Alfven waves in a mirror field.
