Like the North Magnetic Pole, the North Geomagnetic Pole attracts the north pole of a bar magnet and so is in a physical sense actually a magnetic south pole. It is the center of the 'open' magnetic field lines which connect to the interplanetary magnetic field and provide a direct route for the solar wind to reach the ionosphere.
The global definition of the Earth's field is based on a mathematical model. If a line is drawn through the center of the Earth, parallel to the moment of the best-fitting magnetic dipole, the two positions where it intersects the Earth's surface are called the North and South geomagnetic poles.
The north and south geomagnetic poles are the antipodal points where the axis of this theoretical dipole intersects Earth's surface. If Earth's magnetic field were a perfect dipole then the field lines would be vertical at the geomagnetic poles, and they would coincide with the magnetic poles. However, the approximation is imperfect, and so the ...
The south magnetic pole, also known as the magnetic south pole, is the point on Earth's Southern Hemisphere where the geomagnetic field lines are directed perpendicular to the nominal surface. The Geomagnetic South Pole, a related point, is the south pole of an ideal dipole model of the Earth's magnetic field that most closely fits the Earth's ...
A top-down view of the polar latitudes of Earth's Northern Hemisphere, centered on the Geographic North Pole and showing the distinct locations of the actual Magnetic North Pole and the idealized Geomagnetic North Pole as of 2017. Only the Geographic Pole is in a stationary position; the Magnetic and Geomagnetic Poles are both gradually moving ...
The magnetic North Pole differs from the geographic North Pole (Earth's rotation axis), magnetic north which is the direction of north given by a compass, and the theoretical Geomagnetic pole. North Magnetic Pole migration. The search for the magnetic north pole began in 1818 with a British expedition exploring the Northwest Passage.
The Earth’s geomagnetic field, which scientists have been warning about for hundreds of years, isn’t about to suddenly flip over after all, according to a new The Earth's magnetic poles ...
Apparent polar wander (APW) is the perceived movement of the Earth's paleomagnetic poles relative to a continent while regarding the continent being studied as fixed in position. [1] It is frequently displayed on the present latitude-longitude map as a path connecting the locations of geomagnetic poles , inferred at distinct times using ...
