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 …

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.

2024年12月20日 · While the geographical North Pole stays fixed in place (at the very summit of the Earth's rotational axis), the WMM pinpoints the magnetic North Pole – where Earth's magnetic field points straight down, a perfectly vertical magnetic field.

2025年1月21日 · Magnetic north versus ‘true north’ At the top of the world in the middle of the Arctic Ocean lies the geographic North Pole, the point where all the lines of longitude that curve around Earth ...

Magnetic pole may refer to: One of the two ends of a magnet; Magnetic monopole, a hypothetical elementary particle; The magnetic poles of astronomical bodies, a special case of magnets, especially: The North magnetic pole of planet Earth, a point where the north end of a compass points downward

2024年12月17日 · The updated version of the World Magnetic Model was released on Dec. 17, with a new prediction of how the magnetic north pole will shift over the next five years. Here's why it was changed.

The magnetic pole is the region where the external magnetic field is the strongest at each end of a magnet. A pole of a magnet may refer to a magnetic monopole, a hypothetical elementary particle. The magnetic poles of the astronomical bodies are a special case of magnets.

Earth's magnetic field, also known as the geomagnetic field, is the magnetic field that extends from Earth's interior out into space, where it interacts with the solar wind, a stream of charged particles emanating from the Sun.

2024年5月21日 · Magnetic poles are one of the fundamental concepts in magnetism, describing the regions of a magnet where the magnetic force is the strongest. There are two types of magnetic poles: the north pole and the south pole.

2023年9月11日 · Earth is the only rocky body in the inner solar system with strong magnetic poles. But where do these poles come from, and what do they do?
