degaussed
Stripped of magnetism
Degaussed means demagnetized—having had magnetic fields removed or neutralized.
The term comes from the gauss, a unit of magnetic measurement.
Ships are degaussed to avoid triggering magnetic mines.
Computer monitors were degaussed to correct color distortion.
To degauss a hard drive is to erase it completely by scrambling its magnetic data: The classified drives were degaussed before disposal.
