Detailed explanation-1: -Generated by the motion of molten iron in Earth’s core, the magnetic field protects our planet from cosmic radiation and from the charged particles emitted by our Sun. It also provides the basis for navigation with a compass.
Detailed explanation-2: -It deflects most of the solar material sweeping towards us from our star at 1 million miles per hour or more. Without the magnetosphere, the relentless action of these solar particles could strip the Earth of its protective layers, which shield us from the Sun’s ultraviolet radiation.
Detailed explanation-3: -Earth’s magnetic field is also referred to as the geomagnetic field. The earth’s magnetic field extends millions of kilometers into outer space and looks very much like a bar magnet. The earth’s south magnetic pole is actually near the North Pole and the magnetic north pole is in Antarctica!
