degauss
/'di:gaus/
Definition
- Verb:
- To make nonmagnetic; to remove or neutralize the magnetic field of an object. This process involves applying an opposing magnetic field to cancel out the existing magnetism, rendering the object magnetically neutral.
Usage
- The primary use of degauss is in technical and industrial contexts. It describes the action of eliminating unwanted magnetization from objects like metals, electronic components, or entire ships to prevent interference or detection.
- It is a transitive verb, requiring a direct object (the thing being demagnetized).
Examples
- Verb:
- The technician will degauss the old computer monitor to fix the discoloration on the screen.
- To protect the vessel from magnetic mines, the navy must regularly degauss the ship's hull.
- You can degauss a screwdriver by passing it through a special coil.
Advanced Usage
- "Degaussing" as a Gerund/Noun: The process or act of degaussing.
- The degaussing of the data tapes was a standard security procedure.
- Historical/Military Context: Specifically refers to making a ship's metal hull magnetically neutral to avoid triggering magnetic naval mines.
- During World War II, the Allies developed techniques to effectively degauss their warships.
Variants and Related Words
- Degausser (n): A device or tool used to degauss an object.
- He used a powerful degausser to erase the hard drive.
- Degaussing (adj/n): Describing the process or related to it.
- The ship underwent a degaussing procedure.
Synonyms
- Demagnetize: The most direct synonym, meaning to remove magnetic properties.
- Demagnetize the tool before working on sensitive electronics.
Antonyms
- Magnetize: To impart magnetic properties to an object.
Notes
- The term originates from "de-" (meaning to remove or reverse) and "gauss," a unit of magnetic flux density, named after the mathematician Carl Friedrich Gauss.
- In modern computing, degaussing specifically refers to erasing data from magnetic storage media (like old hard drives or tapes) by disrupting the magnetic patterns that represent the data. This is a form of secure data destruction.
Verb
- make nonmagnetic; take away the magnetic properties (of)
- demagnetize the iron shavings
- they degaussed the ship
