North magnetic pole - Wikipedia
The north magnetic pole, also known as the magnetic north pole, is a point on the surface of Earth's Northern Hemisphere at which the planet's magnetic field points vertically downward (in other words, if a magnetic compass needle is allowed to rotate in three dimensions, it …

This dipole defines an axis that intersects Earth's surface at two antipodal points called geomagnetic poles. Based on the WMM2020 coefficients for 2020.0, the Geomagnetic North Pole is at 72.68°W longitude and 80.65°N latitude, and the Geomagnetic South Pole is at 107.32°E longitude and 80.65°S latitude.

Geomagnetic pole - Wikipedia
Like the North Magnetic Pole, the North Geomagnetic Pole attracts the north pole of a bar magnet and so is in a physical sense actually a magnetic south pole. It is the center of the 'open' magnetic field lines which connect to the interplanetary magnetic field and provide a direct route for the solar wind to reach the ionosphere .

Magnetic pole | Earth, Magnetism, Reversal | Britannica
Magnetic pole, region at each end of a magnet where the external magnetic field is strongest. A bar magnet suspended in Earth’s magnetic field orients itself in a north–south direction. The north-seeking pole of such a magnet, or any similar pole, is called a north magnetic pole.
