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. The north magnetic pole moves over time according to magnetic changes and flux lobe elongation [2] in the Earth's outer core. [3]
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 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 actual magnetic field. For historical reasons, the "end" of a freely hanging magnet that points (roughly) north is itself called the "north pole" of the magnet, and the other end, pointing ...
Fernando Cervantes Jr. Updated November 19, 2024 at 6:46 PM. The Earth's magnetic North Pole is currently moving toward Russia in a way that British scientists have not seen before. Scientists ...
And there’s the magnetic North Pole, which is always on the move. And right now it’s moving faster than usual. Over the past 150 years, the magnetic North Pole has casually wandered 685 miles ...
A magnet's North pole is defined as the pole that is attracted by the Earth's North Magnetic Pole when the magnet is suspended so it can turn freely. Since opposite poles attract, the North Magnetic Pole of the Earth is really the south pole of its magnetic field (the place where the field is directed downward into the Earth). [20] [21] [22] [23]
The auroras are best seen around the magnetic poles of the northern and southern hemispheres in places like Europe, Asia and North America. In the U.S., Alaska is well known to have the best ...
The North Magnetic Pole's drift. Polar drift is a geological phenomenon caused by variations in the flow of molten iron in Earth's outer core, resulting in changes in the orientation of Earth's magnetic field, and hence the position of the magnetic north - and south poles. The North magnetic pole is approximately 965 kilometres (600 mi) from ...
