    The difference between the Arctic and the magnetic Arctic lies in that the former is a form of geographical pole and its position is still at 90 ° north latitude The geographical North Pole is also the true north, the northernmost point on the earth, all points facing south The magnetic north pole is not based on true north, but on the earth's magnetosphere It is hundreds of kilometers from the true north and its exact location is constantly changing Like magnets, the earth creates magnetosphere through the magnetic north and south poles The magnetosphere forms a huge charged magnetic field around the earth, and each pole has a shrinking funnel or spire The magnetic north pole marks the point at which the source of the magnetic field is 90 ° down (relative to the surface) from the earth When the solar wind particles explode towards the earth, most of them are deviated by the magnetosphere However, some of the sun's particles slide into the pinnacle, producing auroras or northern lights As the magnetic field changes, the exact location of the magnetic north pole will also shift It moves so fast that some scientists even predict it will surpass Siberia by 2055 Other scientists believe that according to the current record, this migration is likely to be part of the oscillation mode and eventually move the magnetic pole back to Canada The location of the magnetic north pole was first calculated and recorded in 1831 By 1904, it had moved 50 kilometers The geological survey of Canada determined that its position in 2001 was 81.3 ° north latitude, 110.8 ° west longitude, moving northwest at a speed of about 40 kilometers per year The magnetic compass points to the magnetic north pole and the true north It doesn't matter to most people, but if you travel in the Arctic, you have to consider the position of the magnetic north pole to calculate the exact position If possible, the best navigation tool is the global positioning system (GPS).
