A magnet is a material or object that produces a magnetic field. This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials and attracts or repels other magnets.... .
The poles of astronomical bodies are determined based on their axis of rotation in relation to the celestial poles of the celestial sphere.... , a special case of magnets, two special cases of which are the Geomagnetic poles:
The Earth's North Magnetic Pole is the wandering point on the Earth's surface at which the Earth's magnetic field points vertically downwards .... of planet Earth, to which the north end of a compass points.
The Earth's South Magnetic Pole is the wandering point on the Earth's surface where the Earth's magnetic field lines are directed vertically upwards.... of planet Earth, to which the south end of a compass points.
Earth's magnetic field is approximately a magnetic dipole, with one magnetic pole near the north pole and the other near the geographic south pole .... .
