Antarctic magnetism

The earth's magnetic field is not constant forever. Its north and south magnetic poles have once reversed positions, that is, the geomagnetic north pole has changed into the geomagnetic south pole, and the geomagnetic south pole has become the geomagnetic north pole. This is the so-called "magnetic pole reversal." It is now located roughly south of the Ninnis Glacier in George V Land in eastern Antarctica. In 1975, based on new data on the Earth's magnetic field and the flow of charged particles in solar activity, it was changed to 139°24 'east longitude and 65°48' south latitude, near Wilkes Land. After scientific determination, the North Magnetic Pole is moving north at a speed of about 10 kilometers per year. Since it was ascertained in 1909 that the approximate position of the North Magnetic Pole was at George V, the easternmost part of East Antarctica, and its position was confirmed to be at 72°25 'south latitude and 155°16' east longitude, its position was moved to 66°30 'south latitude and 139°54' east longitude in 1965; in 1971, its position was moved to 60°48 'south latitude and 139°24' east longitude. In 1980, it was 139°30 'east longitude and 60°30' south latitude; the current position of the southern magnetic pole is moving from the Antarctic continent to the Southern Ocean.

In theory, when you are at the Antarctic Pole, the S pole of the compass in your hand should overlap with the longitude of 139°24 'east longitude, and at this time the S pole is facing the direction of the geographical North Pole. In fact, due to the change of the magnetic poles of the two poles, after reaching the Antarctic, it is basically slow to respond and the direction indicated is inaccurate.

An Australia scientific team measured the geographical position of the South Magnetic Pole near the Antarctic waters and reached an area only 1.6 kilometers away from the South Magnetic Pole. This is the first time humans have been so close to the South Magnetic Pole.

After arduous efforts, a scientific team led by geologist Dr. Charles Barton finally discovered and determined the geographical location of the South Magnetic Pole. According to detailed calculations, the South Magnetic Pole is located at 64 degrees south latitude and 138 degrees east longitude in the Antarctic Sea. Unlike the geographical north and south poles, the positions of the north and south poles often move, making it difficult to track and grasp.

Dr. Barton has been planning this exploration and research activity for 16 years. He said that although he had made very thorough preparations, he was still surprised to be so close to the Earth's magnetic pole. He said excitedly,"I feel like my dream has come true now. It makes me so excited." It is very exciting to be so close to the south magnetic pole. No one has ever been so close to the earth's south magnetic pole like we have before. Dr. Barton claims that he is now the closest person to the South Pole. Dr. Barton reached just ten kilometers from the south magnetic pole in 1994.
