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 core is believed to have two parts: a solid inner core, with a radius of 1,220 km, and then a liquid outer core that extends to a radius of 3,400 km. The core is through to be 80% iron, as well as nickel and other dense elements like gold, platinum and uranium.
