Which term describes the process of erasing all data on a magnetic hard drive by exposing it to a very strong magnetic field?
Magnetizing
Shredding
Low-level formatting
Degaussing
The correct term is degaussing. A degausser generates an extremely powerful magnetic field that randomizes the magnetic domains on the platters, rendering previously stored data unrecoverable. The other options describe different disposal or preparation methods and do not rely on magnetic fields to sanitize data.
