To make a (steel) ship's hull nonmagnetic by applying an opposing magnetic field.
To remove irregular magnetization in (the electron gun of a cathode-ray tube); -- used to improve picture quality, especially in computer monitors.
The electron "guns" used by a Cathode Ray Tube to create images On the screen, build up electromagnetic charges, and this can cause Image distortion over time. Degaussing your monitor realigns the Guns inside the screen to compensate for any magnetic interference.
The act of de-magnetizing a CRT monitor or magnetic media. Degaussing a CRT monitor is necessary when a monitor has been moved in relation to the Earth's...
To reduce magnetic flux density to zero by applying a reverse magnetizing field.
Ever wonder what that "degauss" button on your monitor does besides make a ...
To remove stray magnetic fields from a computer display.
make nonmagnetic; take away the magnetic properties (of); "demagnetize the iron shavings"; "they degaussed the ship"
Erase a videotape completely by exposing the tape to a magnetic field.
Destroy information contained in magnetic media by subjecting that media to high-intensity alternating magnetic fields, following which the magnetic fields slowly decrease.
To return the magnetization in a media coating or in a head to a zero state by applying a decaying and alternating magnetic field.
To remove magnetism from a device. The term is usually used in reference to color monitors and other display devices that use a Cathode Ray Tube (CRT). These devices aim electrons onto the display screen by creating magnetic fields inside the CRT. External magnetic forces -- such as the earth's natural magnetism or a magnet placed close to the monitor -- can magnetize the shadow mask, causing distorted images and colors. To remove this external magnetic forces, most monitors automatically degauss the CRT whenever you turn on the monitor. In addition, many monitors have a manual degauss button that performs a more thorough degaussing of the CRT. You can also use an external degausser that degausses the monitor from the outside. Since it may be impossible to remove the external magnetic force, degaussing works by re-aligning the magnetic fields inside the CRT to compensate for the external magnetism.
To apply a variable, alternating current (AC) field for the purpose of demagnetizing magnetic recording media. The process involves increasing the AC field gradually from zero to some maximum value and back to zero, which leaves a very low residue of magnetic induction on the media. Degauss loosely means to erase.
The process of eliminating the buildup of stray magnetic fields that alter the electron beam scans. This helps improve image clarity.
To erase data recorded in a magnetic tape.
On monitors, a process that demagnetizes the metal components in the CRT, thus eliminating image distortion that can result from magnetic charges acquired by the components. Some new monitors degauss automatically whenever you turn on your monitor.
Magnetic interference caused by a change in the position of a monitor in relation to the earth's magnetic field or the presence of an artificial magnetic field can cause discolour- ation. To correct this, all colour monitors automatically degauss at power-on and some also have a manual degaussing button. This allows the monitor to compensate for the change in the magnetic field by realigning the electron guns. In some low cost monitors without degauss buttons it is necessary to leave the power turned off for at least 20 minutes in order to get maximum degaussing.
