WebWhat Is Earth’s Magnetic Field. Earth’s magnetic field is also referred to as the geomagnetic field. The earth’s magnetic field extends millions of kilometers into outer space and looks very much like a bar magnet. The earth’s south magnetic pole is actually near the North Pole and the magnetic north pole is in Antarctica! WebJul 6, 2024 · Ongoing monitoring of the Earth's geomagnetic field (which includes the pole) will continue after the WMM release, principally through the European Space Agency Swarm mission, Korte said.
