Plasmasheric Boundary Layer: Plasmapause

A Dipole Magnetic Field: NOT!

The Standard Plasmasphere View

Important Physics happens at the Boundary Layer, John Foster will tell us about this dynamic redistribution of plasma…. but…..

At the boundary layer and in the plasmasphere the cold plasma Interacts with hot plasma: radiation belts and the ring current. These hot particles are guided by a “changing” magnetic fields. The cold boundary layer also has a “hot outer zone” that has a rich ion composition. Did I mention E&M waves…..

Humans can modify the plasmasphere…………..
