Abstract

People's knowledge and utilization of geomagnetic field has been going on for thousands of years, and many hypotheses have been proposed about the origin of geomagnetic field, yet so far none of them is able to completely answer every question about the geomagnetic field, so Einstein once classified the origin of the geomagnetic field as one of the five difficult problems in physics. Recently, the author analyzed the formation and evolution of the Earth as well as its internal structure and external environment again, and has found the origin of the geomagnetic field: the polar vortexes at Earth’s North and South Poles can produce spiral currents, then form a synthesized magnetic dipole at Earth’s North and South Poles respectively, adding the local non-dipole magnetic fields produced by the atmospheric circuits around the clouds there, finally producing the present geomagnetic field. If the Earth enters a glacial period, there is little cloud vaporized from the non-polar regions and moved to the polar regions, so the polar vortexes are very weak, the resulting dipole magnetic fields are weaker than local non-dipole magnetic fields with different polarities, so the superposition of these two kinds of magnetic fields yields a new geomagnetic field with different polarity. This new theory can also reveal the origin of other stars’ magnetic fields and the law of their reversal.
