Earth's Magnetic Field. The existence of Earth's magnetic field itself is evidence that the outer core is liquid. The outer core is believed to contain a system of convection currents that create a dynamo effect, and generates this field.
The inner core which is at the very centre of the Earth is a solid layer approximately 780 miles (1,250 km) thick. The core is at a very high temperature and so the outer core is always molten, however as the depth within the core increase the pressure drives the melting temperature up above the in-situ temperatures even though they reach 6700ÃÂºF (3700ÃÂºC).
