What is the function of the Earth’s magnetic field?

The Earth’s magnetic field serves several important functions, including protecting the planet from harmful solar radiation and cosmic rays. It is generated by the movement of molten iron and other metals in the Earth’s outer core. The magnetic field extends into space and forms the Earth’s magnetosphere, which deflects charged particles from the Sun, preventing them from directly impacting the atmosphere. This protection helps to preserve the Earth’s atmosphere and makes it possible for life to thrive on the planet.
