This is the South Magnetic Pole according to http://www.infoplease.com/ce6/sci/A0831157.html.

Based on Canadian information from:

Here is a Placemark for the approximate locations of the North Magentic Pole since 1831.

Note that the position of the North Pole is ever so slightly off. Exact placement causes the icon to disappear.

South Magnetic Dip Pole was measured on an expedition by ship in year 2000. Often called the "Magnetic South Pole" because compass needles in the antarctic area of the Southern Hemisphere tend to align toward this spot on the earth. Technically, it is called the south magnetic dip pole, and it is at the point on the Earth where a compass needle points straight down towards the gravity center of the earth. The "dip" in the name comes from the geomagnetic instrument called a "dip magnetometer" which determines the angle at which the Earth's magnetic field points into the Earth. The magnetic pole is due to magnetic fields that are generated deep in the Earth's molten metal core, and the core's field axis is not the same as the earth's rotational axis where the Geographic South Pole is at 90 degrees South.

The North Magnetic Dip Pole has been measured accurately much more often by scientists than the South Magnetic Dip Pole. Expeditions to the location of the South Magnetic Dip Pole have been attempted only rarely over the years. On 23 December 2000, the Australian private Antarctic research vessel 'Sir Hubert Wilkins' attained the accurate Magnetic South Pole for what is believed to be the very first time by any ship. The research team located the south magnetic pole at near 65degrees 39minutes South by 140degrees 01minutes East. The previous best attempt at locating the pole was by another team in 1986, when it is believed that they got within 12 kilometers of it. The magnetic pole itself is difficult to attain as it moves around often quite quickly due to the sun's variable effect upon the magnetic field of the earth. When this field measurement was taken in year 2000, the Solar Cycle 23 was at its peak and the earth's magnetic field was dancing rapidly around due to rather intense sunspot activity. According to a report from the measurement team, during their measurements as they approached it, the pole had been moving around at a speed of several hundred kilometres a day, but at the actual time of the attainment the pole's movement had slowed to less than 10 km per hour. The magnetic poles can drift an average of hundreds of kilometers per century. In the early days of 20th century Antarctic exploration, the magnetic pole was located in an area that could be reached "overland" by sled (however difficult). It has since moved out into the Southern Ocean as shown by the yearly green trace line on the following map. The blue trace line shows the track of the Geomagnetic South Pole movement based upon IGRF model.


As you can see on the following map, a compass needle points off from true north by the "magnetic declination", and these changes shown from the 16th through the 20th century are due to magnetic pole movement.

The earth's magnetic field intensity has also changed over time:


IGRF Model Dip Poles

This placemark Magnetic Dip Pole should not be confused with the "IGRF Model Magnetic Dip Pole" or the "Model Dip Pole". The Model Dip Pole is different, and its position depends upon which model is used for the magnetic Gauss coefficients of the spherical harmonic analysis obtained from the best fitting of data from observatories at different points on the earth.

It has been told by actual studies, that the magnetic north pole is moving, so this point isn't really the magnetic north pole.
