Rock magnetism - Wikipedia

Rock magnetism is the study of the magnetic properties of rocks, sediments and soils.The field arose out of the need in paleomagnetism to understand how rocks record the Earth's magnetic field. This remanence is carried by minerals, particularly certain strongly magnetic minerals like magnetite (the main source of magnetism in lodestone).An understanding of remanence helps paleomagnetists to ...

does limestone have magnetic properties

Magnetic Properties. If a metal is placed in a magnetic field, a force is exerted on it. The intensity of the magnetization, called M, can be measured in terms of the force exerted and its relation to the magnetic field strength, H, depending upon the susceptibility, K, which is a property of the metal. ...
