viscous magnetization
1Natural remanent magnetization — (NRM) is the permanent magnetism of a rock or sediment. In some forms, it can preserve a record of the Earth s field and the tectonic movement of the rock over millions of years. Natural remanent magnetization forms the basis of paleomagnetism… …
