Term derived from Johann Gauss who was a mathematician who studied and
worked with electro-magnetic fields. Degauss is a method of erasing
magnetic media and the removal of remnants of previously recorded
signals. The degauss process is achieved by passing magnetic media
through a magnet field more powerful than the media itself in order to
rearrange the magnetic particles.
Degaussing was first used
by the British Royal Navy in the 2nd WW. An electro-magnetic cable was
inserted on the inside and around each warship as a safeguard against
magnetic mines. Each time a ship came into harbor it was degaussed. An
electrical current was passed through this cable and the magnetic field
was neutralized, hence the magnetic mine was unemployed.
