the process of making a (steel) ship's hull nonmagnetic by producing an opposing magnetic field.
the process of removing data from magnetic storage media by means of electro-magnetic energy.
When a ship leaves port it can go over the degaussing range to demagnetize the hull.
Restoring picture quality with the use of a wand or buttons to remove smears of colour from the video screen.
degaussing or demagnetizing describe the use of an external degausser or bulk eraser erase data from magentic media.
removing magnetism from a CRT or other electronic device
Technique used to remove the magnetic field from Teledyne RDI battery packs before installation, done to minimize any effects the batteries will have on the magnetic compass.
The process of removing the magnetism from a magnetically recorded tape or disk, thus erasing its contents.
To reduce magnetic induction to zero by applying a reverse magnetizing field. Also called "demagnetizing."
The process of erasing all sound from a piece of magnetic stock or tape.
The process of demagnetizing (removing the magnetic field) of a monitor that can build up over time or occur from external sources, to remove the color or picture distortion caused by the field.
Magnetic stripe data erasure.
Degaussing is the process of reducing or eliminating an unwanted magnetic field. It is named after Carl Friedrich Gauss, an early reseacher in the field of magnetism. Due to magnetic hysteresis it is generally not possible to reduce a magnetic field completely to zero, so degaussing typically induces a very small "known" field referred to as bias.
