The models show a ridge (a) about 5 million years ago (b) about 2 to 3 million years ago and (c) in the present.Paleomagnetism (or palaeomagnetism in the United Kingdom) is the study of the record of the Earth's magnetic field in rocks, sediment, or archeological materials.Paleomagnetists led the revival of the continental drift hypothesis and its transformation into plate tectonics.

In the 19th century studies of the direction of magnetization in rocks showed that some recent lavas were magnetized parallel to the Earth's magnetic field. Blackett provided a major impetus to paleomagnetism by inventing a sensitive astatic magnetometer in 1956.

The paleomagnetic tool is mainly used to determine movements of the main tectonic plates and paleocontinental reconstruction (e.g.Certain minerals in rocks lock-in a record of the direction and intensity of the magnetic field when they form.

This record provides information on the past behavior of Earth's magnetic field and the past location of tectonic plates.The other method adopts a Matlab tool using a Bayesian statistics with global geomagnetic field prediction model (ARCH3K.1).
