| Abstract: | By use of the separation of the interior and exterior geomagnetic fields the equivalent current systems of interior and exterior geomagnetic field are inversed.The relations between the geomagnetic “lowest shift” phenomenon and the equivalent current systems are studied.The results show there is clear relation between them，so，the change of equivalent current systems may be one of causes of the geomagnetic “lowest shift”. |
