Causes of Geomagnetism

Abstract

The purpose of this research is to research the causes of geomagnetism. For the method, the Earth's matter and the Earth's magnetic field were investigated. As a result, the Earth's equator is hot, the north and south poles are cold, the center of the Earth is hot, and the surface of the earth is cold. This temperature difference generates an electromotive force, and this electromotive force creates a magnetic field. The Earth behaves as if an electric motor and generator were combined. Therefore, an additional current flow and a magnetic field are generated to function as an electromagnet. As the Earth rotates, it functions as a generator. Therefore, geomagnetism is the sum of the Earth's permanent magnet and the electromagnet caused by the Earth's rotation. The conclusion is that geomagnetism is caused by the electromotive force of the earth's temperature difference and the electromotive force of the earth's rotation.
