Earthâs magnetic field is generated by an interaction between rotation in the planetâs core and electrical currents.The field then creates the magnetosphere, which acts sort of like a force field, protecting the planet from the brunt of the sun's solar wind.arthâs magnetic field is generated by an interaction between rotation in the planetâs core and electrical currents.
Typically each newly generated field lines up in the direction of the existing magnetic field. But every now and again, some force will cause the new field to line up in the opposite direction. This process can lead to a net weakening of Earth's magnetic field. Over time a new field can continue to grow. This further weakens the original magnetic field. If the process continues, the two fields would eventually cancel each other out.
