We assume that the interparticle distances to be larger than the Debye shielding length, so that interparticle Coulomb interactions are negligible. In order to evaluate the different currents, we need to know the details of the parameters of the plasma in which the particles are immersed. 1 Solar wind Outside Earth's magnetosphere. Geosynchronous plasma environment Outside plasmasphere out to approx. Plasmasphere Inside 4 to 5 R E .
Outer boundary has local time variations.
