Inside the plasmapause the magnetospheric convection electric field is mostly, but not completely, absent. As a consequence, the thermal plasma of the plasmasphere tends to rotate with the earth, or at least with the atmospheric regions between 100 to 150 km where dynamo electric fields are generated.
