What does degausser mean?
A degausser is a device that removes or neutralizes unwanted magnetism. It is used in electronics and magnetic-media work, for example to clear magnetic buildup from recording equipment or to restore the color alignment of a cathode-ray television. The name combines the prefix de-, suggesting removal or reversal, with Gauss, the surname of the German mathematician and physicist Carl Friedrich Gauss, who is also commemorated by the gauss, the unit of magnetic flux density. The related verb degauss means to demagnetize something, but degausser specifically names the apparatus that performs the operation. Although once especially associated with consumer cathode-ray televisions, degaussers also have specialist uses in magnetic recording, data storage, and the maintenance of sensitive electronic equipment.
nounA device or apparatus used to neutralize or remove unwanted magnetism, especially from a magnetic recording, electronic instrument, or cathode-ray tube.
- A device used to demagnetize an object or counteract unwanted magnetic fields, such as those affecting magnetic recordings or cathode-ray tubes.
"The technician used a degausser to remove the magnetic distortion from the reel-to-reel tape."
"A degausser was used to clear the magnetic buildup affecting the recording head."
"The old television required a degaussing coil to restore a properly aligned picture."
The plural is used when referring to multiple degaussing devices or pieces of equipment.
"The workshop owns several degaussers for servicing recording equipment."
A degausser literally lets you undo a magnetic field—and once did essential work behind every properly adjusted cathode-ray television.

Where does degausser come from?
Degausser is formed in English from de- and Gauss, the surname of German mathematician and physicist Carl Friedrich Gauss. The prefix de- indicates removal or reversal, reflecting the device's function of eliminating a magnetic condition. The name also connects with the gauss, the unit of magnetic flux density named after Gauss, and with related terms such as degauss and gaussmeter.
How degausser is actually used
This is chiefly a technical noun in electronics, media preservation, and servicing. The related verb degauss is more common when referring to the action of removing unwanted magnetism.
Easily confused with degausser
A degausser is a specific device that removes or neutralizes magnetic fields, while a demagnetizer is the broader term for any device or material used for that purpose.
