So paleomagnetism can really be thought of as the study of an ancient magnet field. Some of the strongest evidence in support of the theory of plate tectonics comes from studying the magnetic fields surrounding oceanic ridges.
Paleomagnetism relied heavily on new developments in rock magnetism, which in turn has provided the foundation for new applications of magnetism. These include biomagnetism, magnetic fabrics (used as strain indicators in rocks and soils), and environmental magnetism.
