WebThe ionospheric dynamo region between about 100 to 200 km altitude is a region where ions and electrons have different mobility. Thus the plasma becomes electrically conducting. Due to the geomagnetic field, two kinds of electric currents exist: Pedersen currents parallel to E , and Hall currents orthogonal to E and B . Webfields, due to ionospheric and magnetospheric current systems that induce image currents deep in Earth, can be used to infer mantle electrical conductivity (2218). These magnetovariational induc– - tion methods, which require accurate models of the external source fields, have been most successfully applied to long-period (> 2 day)
