Field aligned currents
WebIn geomagnetic field: Field-aligned currents. Circulation of magnetic field lines in a pattern of closed loops within the magnetosphere is a consequence of the tangential drag of the solar wind. This circulation produces another important magnetic field source, the field-aligned current system. The field-aligned currents flow on two…. Read More. WebFeb 1, 2001 · A pair of field aligned currents separated in the east-west sense and moving westward (tailward on the dawn side) at 4–5 km/s is consistent with the data, producing a twin vortex pattern of Hall currents. There are no discrete auroral emissions coincident with the downward Birkeland current. The first auroral forms are faintly shown to the ...
