The formation of the problem concerning calculation of the electric field and field-aligned currents in the magnetosphere
and ionosphere produced by asymmetric ring current is considered with the approach and equations developed by [1–3]. These
equations were used previously for estimation of the electric field in the ionosphere and magnetosphere appearing in the process
of spreading of energetic particles injected into the trapping zone of the magnetosphere as a result of nuclear explosion.
According to this theory, energetic particles injected into a ring current produce an asymmetric divergent ring current, field-aligned
currents, a global electric field and currents in the ionosphere.

Modeling of field-aligned currents produced by asymmetric ring current during strong magnetic storms
The modeling of field-aligned currents (FACs) produced by an asymmetric ring current is presented. Our first results of the
modeling of FACs in the magnetosphere, which were based on the theory advanced in [1–5], were obtained in [6]. It was shown
that FACs develop as spiral structures. Extending this work, we came to the conclusion that FACs, appearing in the magnetosphere
and ionosphere as a result of ion or electron injections, generally develop as clockwise (ion injections) or anticlockwise
(electron injections) spirals that are independent of the number and energy spectra or space distributions of injected particles.
A sharp maximum of FACs or an FAC jet in such spirals can be present at middle latitudes. The value of currents in a midlatitudinal
FAC jet during strong magnetic storms and substorms could be of the same order as experimentally observed in the polar region.
The model presented describes the dependence of ion FACs as well as FAC jets in the magnetosphere and ionosphere, on the parameters
of injected particles.
