Geomagnetic North Pole

There are three kinds of pole: magnetic, geographic and geomagnetic. The Geomagnetic North Pole, the least well-known of all, comes from a mathematic model supposing that the Earth behaves like a perfect magnetic dipole, which is not in reality exact, since the Magnetic North and South Poles and the centre of the Earth are not aligned. This model enables scientists to better apply the physics concepts that we know. The position of the Geomagnetic North Pole is therefore defined by calculations and changes constantly, following the movements of the Magnetic North Pole. In 1951, then located in Greenland at 78° 29’ N and 68° 54’ W, it was reached by Jean Malaurie. It can currently be found on Ellesmere Island.
