How does paleomagnetism relate to seafloor spreading?

Paleomagnetism (occasionally palaeomagnetism ) 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.
