For historical reasons, the "end" of a freely hanging magnet that points (roughly) north is itself called the "north pole" of the magnet, and the other end, pointing south, is called the magnet's "south pole". Because opposite poles attract, the Earth's South Magnetic Pole is physically actually a magnetic north pole (see also North Magnetic Pole § Polarity). | For historical reasons, the "end" of a freely hanging magnet that points (roughly) north is itself called the "north pole" of the magnet, and the other end, pointing south, is called the magnet's "south pole".

The South Magnetic Pole is constantly shifting due to changes in the Earth's magnetic field. As of 2005 it was calculated to lie at 64°31′48″S 137°51′36″E, placing it off the coast of [[Antarctica]], between [[Adélie Land]] and [[Wilkes Land]]. In 2015 it lay at 64.28°S 136.59°E (est). That point lies outside the [[Antarctic Circle]]. Due to polar drift, the pole is moving northwest by about 10 to 15 kilometers (6 to 9 mi) per year.

Its current distance from the actual Geographic [[South Pole]] is approximately 2,860 km (1,780 mi). The nearest permanent science station is Dumont d'Urville Station. Wilkes Land contains a large gravitational mass concentration. | ||
