How heat is produced from the core

WebAs a result, the geodynamo, or magnetic field in the Earth's core, is produced by the heat transfer from the inner to the outer core. The magnetic field that surrounds the Earth and interacts with the solar wind to produce phenomena like the Northern and Southern Lights is created by the geodynamo. Earth's internal heat budget is fundamental to the thermal history of the Earth.
