Abstract:

A critical analysis of the theoretical methods for obtaining the ionospheric and induced currents from the geomagnetic variations is performed, and the ionospheric currents in the electrojet are analyzed, through the geomagnetic variations in the proximity of the dip equator in Nigeria. For this purpose, a method, previously introduced by the authors, is applied, which makes it possible to discuss the contribution of the currents induced in the Earth by those variations. The result is compared with that obtained from the variations in the South American area. It is found that the amplifications could be very different in the two areas. © 1981.
