The layer inside the Earth that creates its magnetosphere is the outer core, which is composed of liquid iron and nickel. The movement of this molten metal generates electric currents, which in turn produce magnetic fields. The dynamic processes in the outer core are responsible for the geodynamo effect, creating the Earth's magnetic field that extends into space as the magnetosphere. This magnetic field protects the Earth from solar wind and cosmic radiation.
