geomagnetic field

The geomagnetic field is like a giant magnet surrounding the Earth, generated by the movement of molten iron in its core. This magnetic field protects us from harmful solar radiation, guides compasses, and influences many natural processes. It extends from Earth's interior out into space, creating the magnetosphere, which deflects high-energy particles from the Sun. The Earth's magnetic poles can shift over time, and sometimes even reverse, in a process called geomagnetic reversal. Overall, this magnetic field is vital for maintaining conditions that support life and enabling technologies like navigation.
