Study on Magnetic Materials with Numerical Calculation of Geoelectromagnetic Field in Middle-Low Latitude Region

Abstract:

This paper expounds mechanism of the interact between the vary ionosphere currents and the Earth as a magnetic materials during magnetic storms which create the geoelectromagnetic fields on the Earths surface. Cauchy Distribution model of ionosphere currents above the middle-low latitude area is built for calculation of the fields. In order to predict and evaluate the levels of GIC flowing in technology systems,Complex Image Method (CIM) is applied to calculate geo-electric-magnetic fields on the Earths surface of the middle-low latitude. To test veracity,we compare calculation of the electromagnetic field by Complex Image Method and data measured practically. The good accuracy of CIM here is obtained. i.e,CIM can perform well in Middle-Low latitude area.
