Oops that is incorrect. 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.

Update: Michael B., a visitor of Computer Hope, also indicated that 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.

When degaussing a monitor the degauss demagnetizes the CRT, fixing possible color impurities. After either the Degauss button is pressed or the monitor is manually Degaussed the degaussing circuit will be activated and then deactivated after a few seconds. Older monitors may not have this ability however handheld monitor degauss can also be used to restore color impurities. Additional Information on Monitors can be found on our monitor page.
