The electrodynamic consequences of field-aligned fluxes of charged particles in the earth's magnetosphere
Abstract
A theoretical study is presented of electric fields in the magnetosphere and ionosphere induced by noncompensated field-aligned fluxes of superthermal and high-energy charged particles. It is shown that the efficiency of generation of electric fields by photoelectron fluxes is small, and that the photoelectron currents are compensated by cold-plasma currents. In the case of an anomalous drop in field-aligned conductivity, the noncompensated fluxes at high latitudes can generate significant transverse and longitudinal ionospheric electric fields.
