Changes and movements of the south magnetic pole

The earth's magnetic field is not eternal. Its north and south magnetic poles have been reversed, that is, the geomagnetic north pole has become the geomagnetic south pole, and the geomagnetic south pole has become the geomagnetic north pole. This is called "pole inversion". It is now located in the south of ninisz Glacier George V in the East Pole. 1975, according to the new data about the earth's magnetic field and charged particle flow in solar activity, it was changed to the vicinity of Wilkes land at east longitude139 24' and south latitude 65 48'. According to scientific determination, the north magnetic pole moves northward at a speed of about 10 km per year. It is found from 1909 that the general orientation of the north magnetic pole is located at the easternmost part of the southeast pole of George V, and its position is confirmed at 72 25' south latitude and15516' east longitude. By 1965, its position had moved to 66 30' south latitude and 65438+ east longitude. 197 1 year, moving to 60 48' south latitude and 0/39 24' east longitude. 139 30' E and1980 at 60 30' E; At present, the position of the south magnetic pole is moving from the Antarctic continent to the southern ocean.

Theoretically, when you are in the South Pole, the S pole of the compass in your hand should coincide with the east longitude 139 24', at which time the S pole is facing the geographical North Pole. In fact, due to the change of polar magnetic poles, when we reach the South Pole, we are basically slow to respond and the direction indicated is not accurate.
