North Magnetic Pole

Suomi فارسی Tiếng Việt Українська Ελληνικά 日本語 Português Español Русский Română Français 中文 Dansk Svenska العربية 한국어 Čeština Norsk (Bokmål) Català Türkçe

The north magnetic 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 will point straight down). There is only one location where this occurs, near (but distinct from) the geographic north pole. The geomagnetic north pole is the northern antipodal pole of an ideal dipole model of the Earth's magnetic field, which is the most closely fitting model of Earth's actual magnetic field.
