demagnetization
Losing magnetic properties
Demagnetization is the removal or reduction of magnetic properties from something.
Magnets can lose their magnetism through heat, impact, or exposure to opposing magnetic fields.
Hard drives undergo demagnetization (degaussing) to erase data.
The verb is demagnetize: The technician demagnetized the old tapes before disposal.
