Use this interactive map to view experimental and modeled pole locations for 1590–2025. Launch Interactive Map. Observed north dip poles during 1831–2007 are yellow squares. Modeled pole locations from 1590–2025 are circles progressing from blue to yellow. Observed south dip poles during 1903–2000 are yellow squares.

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 …

2019年2月10日 · An interesting map showing the locations of North Magnetic Pole since 1590. Today, it differs the Geographic North Pole by about 500 kilometers (311 miles).

2025年1月21日 · British explorer Sir James Clark Ross discovered the magnetic north pole in 1831 in northern Canada, approximately 1,000 miles (1,609 kilometers) south of the true North Pole.

2025年1月23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. Magnetic north has shifted a lot over the centuries. (BGS) And as the iron and nickel inside our planet ...

Magnetic declination, sometimes called magnetic variation, is the angle between magnetic north and true north. Declination is positive east of true north and negative when west. Magnetic declination changes over time and with location.

2023年6月2日 · As the earth's magnetic field varies over time, the positions of the north and south magnetic poles gradually change. The magnetic declination at a given location also changes over time. This map displays historical isogonic lines and …
