A notional circle on the earth's surface, the plane of which is equidistant between the north and south magnetic poles and perpendicular to the magnetic field.
Example sentencesExamples
The electron concentration is thus depleted on the geomagnetic equator and enhanced in two regions, which locate approximately north and south 15° of the geomagnetic equator.
This occurs only for a signal path peropendicular to the geomagnetic equator, what is also true for VHF scattering from auroras.
Between 20º north and 20º south of the geomagnetic equator the ionosphere bends forming a protuberance.
These models use the International Geomagnetic Reference Field, which accurately describes the relative positions of the geographic and geomagnetic equators and the declination of the magnetic field lines.
This is important as the physical and geomagnetic equators are not aligned in most parts of the world.
