Answer
The Earth's magnetic field is generated by its core, which is composed mainly of iron and nickel. The movement of molten iron in the outer core creates electric currents, which in turn produce the magnetic field. This magnetic field acts as a shield, protecting our atmosphere from harmful solar winds
