Ships are mainly constructed of steel, causing them to disturb the Earth's magnetic field. This makes them easily detected by magnetically activated mines. Ship degaussing is the process of making a (steel) ship's hull nonmagnetic by producing an opposing magnetic field. Installing degaussing systems to mask a ship's magnetic signature makes the ship virtually undetectable by magnetic mines, which greatly increases a ship's survivability.
