Earth's magnetic field - Wikipedia
The inclination of the Earth's field is 90° (downwards) at the North Magnetic Pole and –90° (upwards) at the South Magnetic Pole. The two poles wander independently of each other and are not directly opposite each other on the globe.

2023年11月28日 · The historical movement of these poles indicates a change in the global geometry of the Earth's magnetic field. It may even indicate the beginning of a field reversal – a "flip" between the north and south magnetic poles.
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 …
The Magnetic North Pole Has Officially Changed Position
2024年12月20日 · Magnetic north has shifted a lot over the centuries.

Geomagnetic field | Definition, Strength, & Facts | Britannica
2024年12月29日 · Geomagnetic field, magnetic field associated with Earth. It is primarily dipolar (i.e., it has two poles, the north and south magnetic poles) on Earth’s surface. Away from the surface the dipole becomes distorted. The field is variable, changing continuously, and its poles migrate over time.
