WebThe magnetic field of a dipole is vertical along the polar axis and horizontal along the equator, as can be seen from the bar-magnet figure. These properties lead to definitions of equator and pole in Earth’s more complex field. Thus, the geomagnetic equator is defined as the line around Earth’s surface where the actual field is horizontal. dahlia formby delightWebGeomagnetic Calculators, Maps, Models and Software.
