demagnetization
/'di:,mægnitai'zeiʃn/
Definition
Noun 1. The process of removing magnetization: The act or procedure of eliminating or reducing the magnetic properties of a material, causing it to lose its magnetic field.
Usage
Demagnetization is a technical term used primarily in physics, engineering, and materials science. It describes the deliberate action of making a magnetized object non-magnetic. This can be achieved through various methods, such as heating, hammering, or applying a reverse magnetic field.
Examples
- The demagnetization of the hard drive was necessary to securely erase all data.
- A common method for the demagnetization of a permanent magnet is to heat it above its Curie temperature.
- The technician performed a demagnetization on the tool to prevent it from attracting metal shavings.
Advanced Usage
- Degaussing: A specific technical term often used synonymously with , especially for ships or cathode-ray tube monitors, to neutralize magnetic fields.
- The ship underwent degaussing to protect it from magnetic mines.
Variants and Related Words
- Demagnetize (verb): To remove the magnetic properties from something.
- You can demagnetize a screwdriver by tapping it with a hammer.
- Demagnetizer (noun): A device used to remove magnetization.
- He used a tape head demagnetizer on the audio recorder.
Synonyms
- Degaussing (specific technical context)
