Magnetic memory
Encyclopedia
Magnetic memory may refer to:
- Magnetic storageMagnetic storageMagnetic storage and magnetic recording are terms from engineering referring to the storage of data on a magnetized medium. Magnetic storage uses different patterns of magnetization in a magnetizable material to store data and is a form of non-volatile memory. The information is accessed using...
, the storage of data on a magnetized medium - RemanenceRemanenceRemanence or remanent magnetization is the magnetization left behind in a ferromagnetic material after an external magnetic field is removed. It is also the measure of that magnetization. Colloquially, when a magnet is "magnetized" it has remanence...
, or residual magnetization, the magnetization left behind in a ferromagnet after an external magnetic field is removed - Rock magnetismRock magnetismRock 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...
