Polar drift

Polar drift is a geological phenomenon caused by variations in the flow of molten iron in Earth's outer core, resulting in changes in the orientation of Earth's magnetic field, and hence the position of the magnetic north and south poles.

The magnetic north pole is approximately 965 kilometers from the geographic north pole. The pole drifts considerably each day, and since 2007 it moves about 55 to 60 km per year as a result of this phenomenon.
