How the Earth is Magnetic
E.SE.06.61 - Describe the Earth as a magnet and compare the magnetic properties of the Earth to that of a natural or manufactured magnet.
E.SE.06.62 - Explain how a compass works using the magnetic field of the Earth, and how a compass is used for navigation on land and sea.

The mantle maintains a convection current, creating a magnetic field. A compass works by pointing to 'magnetic north,' or the point where the convection currents meet.
