NORTH POLE: Arctic Ocean– 90ºN
The north pole, also known as the geographic north pole, is one of two places on the surface of a planet coincident with the axis of rotation; it is opposite the south pole. All celestial bodies have a north pole and a south pole, whose axis of rotation is usually not perpendicular to the axis of translation. Thus, those of the Earth form an angle of 23.5º and those of Uranus 97º.
The geographical north terrestrial pole is located in the Arctic Ocean, where the sea is covered by an ice cap or sea ice.
Apart from the geographic north pole, there are other related poles: the celestial north pole, the pole of inaccessibility, the magnetic pole and the geomagnetic pole.
The north celestial pole is an imaginary point, intersection of the axis of terrestrial rotation with the celestial sphere.
The north pole of inaccessibility is the point in the Arctic Ocean furthest from all the surrounding lands. It is currently at 84 ° 03 ‘North, 174 ° 51’ West.
The north magnetic pole is the northern area in which the geomagnetic field has a direction perpendicular to the earth’s surface. The north magnetic pole is not a point, but a large area. A compass placed horizontally on this pole does not orient its needle, being perpendicular to the lines of magnetic force, and if it is placed in such a position that it is parallel to these lines, the needle will point to the earth’s surface. The position of the north magnetic pole moves continuously at a variable speed of about 10km per year in historical time, although it has recently increased to 40km per year, due to the periodic investments of the earth’s magnetic field, several times in the southern hemisphere; the last investment took place 780,000 years ago. At the moment it is located to about 1600km of the geographic north pole, near the Island of Bathurst, in the northern part of Canada, in the territory of Nunavut. Keep in mind that despite being called magnetic north pole for historical reasons, in reality the north magnetic pole is currently a south pole.
The north geomagnetic pole is the point of the magnetic north pole closest to the geographic north pole.
