Plasma sheet

In the magnetosphere, the plasma sheet is a sheet-like region of denser (0.3-0.5 ions/cm3 versus 0.01-0.02 in the lobes) hot plasma and lower magnetic field located on the magnetotail and near the equatorial plane, between the magnetosphere's north and south lobes.[1]

The origin of the plasma sheet is still a subject of discussion on magnetospheric physics[2] but it is thought that the region plays an important role on the transport of plasma around the Earth from the magnetotail towards the Sun. The plasma sheet is closely related to the convective motion of plasma on the magnetotail occurring as a result of magnetic field reconnection.
