The outer core of the Earth is responsible for generating its magnetic field through a process driven by the convection of molten metal. This convection is caused by the extreme heat in the Earth's interior, which causes the molten metal to rise and sink in a continuous cycle. As the molten metal moves, it generates electrical currents through a process known as electromagnetic induction. These electrical currents in turn generate a magnetic field that is aligned with the rotation axis of the Earth.
