Lodestones are naturally magnetized pieces of the mineral magnetite. [1] [2] They are naturally occurring magnets, which can attract iron. The property of magnetism was first discovered in antiquity through lodestones. [3]
[7] [8] With the exception of extremely rare native iron deposits, it is the most magnetic of all the naturally occurring minerals on Earth. [7] [9] Naturally magnetized pieces of magnetite, called lodestone, will attract small pieces of iron, which is how ancient peoples first discovered the property of magnetism. [10]
Natural remanent magnetization is the permanent magnetism of a rock or sediment. This preserves a record of the Earth's magnetic field at the time the mineral was laid down as sediment or crystallized in magma and also the tectonic movement of the rock over millions of years from its original position.
Magnetic mineralogy is the study of the magnetic properties of minerals. The contribution of a mineral to the total magnetism of a rock depends strongly on the type of magnetic order or disorder. Magnetically disordered minerals (diamagnets and paramagnets) contribute a weak magnetism and have no remanence.
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).
The magnetic field of the Earth aligns the domains, leaving the iron a weak magnet. Drawing of a medical treatment using magnetic brushes. Charles Jacque 1843, France. Magnetism was first discovered in the ancient world when people noticed that lodestones, naturally magnetized pieces of the mineral magnetite, could attract iron. [3]
