What does the inner core do?
Despite its small volume (less than 1% of the Earth's volume), the Earth's inner core contains about 10% of the total magnetic field energy. It plays a crucial role in outer core liquid motions and the geodynamo, which generates the Earth's magnetic field. Without the magnetic field, life on Earth would be impossible.
