WebPaleomagnetism (occasionally palaeomagnetism [note 1] ), is the study of magnetic fields recorded in rocks, sediment, or archeological materials. Geophysicists who specialize in paleomagnetism are called paleomagnetists. Certain magnetic minerals in rocks can record the direction and intensity of Earth's magnetic field at the time they formed. WebDec 16, 2024 · Paleomagnetism is the study of the record of earth’s magnetic field with the help of magnetic fields recorded in rocks, sediment, or archaeological materials. The polarity of the Earth’s magnetic field and magnetic field reversals are thus detectable by studying the rocks of different ages.
