Bg. Gavrilov et al., THE INVESTIGATION OF THE FIELD-ALIGNED CURRENT GENERATION DURING THE INJECTION OF PLASMA-JET INTO THE MAGNETOSPHERE, Geomagnetizm i aeronomia, 34(5), 1994, pp. 16-21
Field-aligned currents (FAC) are generated at plasma jet injection per
pendicular to magnetic field lines. The FAC propagate with Alfven velo
city and are connected in the ionosphere. The electrons heating produc
es aurora and ionospheric plasma density enhancement. The value of the
Pedersen conductivity determines the current increasing and jet decel
eration by the electrodynamical force.
