Detailed explanation-1: -The magnetosphere, together with Earth’s atmosphere, still continue to protect our planet from cosmic rays and charged solar particles, though there may be a small amount of particulate radiation that makes it down to Earth’s surface.
Detailed explanation-2: -The Earth’s magnetic field is mostly caused by electric currents in the liquid outer core. The Earth’s core is hotter than 1043 K, the Curie point temperature above which the orientations of spins within iron become randomized.
Detailed explanation-3: -The generation of Earth’s magnetic field occurs deep within the Earth’s interior, in a layer known as the outer core to be precise. Here the convective energy from the slow-moving molten iron is converted to electrical and magnetic energy, according to the U.S. Geological Survey (opens in new tab).
