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.
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.
As of early 2019, the magnetic north pole is moving from Canada towards Siberia at a rate of approximately 55 km (34 mi) per year. [20] NOAA gives the 2024 location of the magnetic north pole as 86 degrees North, 142 degrees East. By 2025, it will have drifted to 138 degrees East (same latitude). [21]
As a result, magnetic north is always changing, and since its discovery in 1831, it has moved roughly 680 miles toward Siberia from its originally documented location.
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 the geographic North Pole. The pole ...
Compass needles in the Northern Hemisphere point toward the magnetic North Pole, although the exact location of it changes from time to time as the contours of Earth’s magnetic field also change.
The Brigantine, Caravel, Corvette and Shamrock gas fields are located in the adjacent UK Offshore Blocks 49/19, 49/20 and 49/24. Brigantine, Caravel and Corvette follow Shell’s convention of naming southern North Sea fields after types of sailing vessels. Brigantine has four gas accumulations designated A-D.
N g is geographic or true north, N m is magnetic north, and δ is magnetic declination. Magnetic declination (also called magnetic variation) is the angle between magnetic north and true north at a particular location on the Earth's surface. The angle can change over time due to polar wandering.
