The Plasma Sheet
The plasma sheet
is just that, a sheet of plasma
that extends down the magnetotail dividing the two lobes of the Earth's magnetic field.
This outer plasma is hotter than the plasma in the plasmasphere, but is considered low energy when compared to the particles in the Van Allen radiation belts.
