Since the magnetospheric plasma is collisionless, the existence of electric fields parallel to the geomagnetic field was a great surprise--the parallel conductivity of the plasma was expected to be very high, and parallel electric fields should be efficiently short-circuited by currents flowing along the magnetic field lines.
