WebThe magnetic field of the earth is caused by a macroscopic electric current, analogous to the magnetic field generated by a hollow solenoid. There is a bistable electric current at the equator of the earth and in the molten core that causes the magnetic field of the earth. The electric current at the equatorial core is ‘self-generated’, which is Earth's magnetic field deflects most of the solar wind, whose charged particles would otherwise strip away the ozone layer that protects the Earth from harmful ultraviolet radiation. One stripping mechanism is for gas to be caught in bubbles of magnetic field, which are ripped off by solar winds.
