Geomagnetic pole - Wikipedia
WEBThe geomagnetic poles are antipodal points where the axis of a best-fitting dipole intersects the surface of Earth. This theoretical dipole is equivalent to a powerful bar magnet at the center of Earth, and comes closer than any other point dipole model to describing the magnetic field observed at Earth's surface.
Earth's magnetic field - Wikipedia
WEBEarth's magnetic field, also known as the geomagnetic field, is the magnetic field that extends from Earth's interior out into space, where it interacts with the solar wind, a stream of charged particles emanating from the Sun.

WEBThis dipole defines an axis that intersects Earth's surface at two antipodal points called geomagnetic poles. Based on the WMM2020 coefficients for 2020.0, the Geomagnetic North Pole is at 72.68°W longitude and 80.37°N latitude, and the Geomagnetic South Pole is at 107.32°E longitude and 80.37°S latitude.
North magnetic pole - Wikipedia
WEBThe 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]

WEBMagnetic Poles and Magnetic Center. Based on the WMM2020 coefficients for 2020.0 the geomagnetic north pole is at 72.68°W longitude and 80.65°N latitude, and the geomagnetic south pole is at 107.32°E longitude and 80.65°S latitude. The axis of the dipole is currently inclined at 9.41° to Earth's rotation axis.

WEBSep 28, 2024 · Geomagnetic field, magnetic field associated with Earth. It is primarily dipolar (i.e., it has two poles, the north and south magnetic poles) on Earth’s surface. Away from the surface the dipole becomes distorted. The field is variable, changing continuously, and its poles migrate over time.
Earth’s magnetic field
WEBThis dynamic force, generated by the movement of liquid iron in Earth’s outer core, undergoes periodic changes and experiences magnetic north-south flips every few hundred thousand years. Earth’s magnetic field has long been used to aid navigation by aligning compasses to the North pole.

WEBWhere are the magnetic poles? The geomagnetic poles or geocentric dipole, can be computed from the first three Gauss coefficients from a main field model, such as the WMM or IGRF. Based on the WMM2020 coefficients for 2020.0 the geomagnetic north pole is at 72.68°W longitude and 80.65°N latitude, and the geomagnetic south pole is …

WEBSep 9, 2022 · The geographic poles are the points where the axis the Earth rotates around meets the surface, and are antipodal (symmetrically opposite) at \ ( {+} {/} {-}90^ {\circ }\) latitude. Our “magnetic” Planet is associated with the geomagnetic field that has a south (north) pole of a magnet near the north (south) pole.
