A device that generates coercive magnetic force for the purpose of reducing magnetic flux density to zero on media is called:
A.
Magnetic saturation
B.
Magnetic field
C.
Physical destruction
D.
Degausser
Explanation:
A degausser is a device that generates a magnetic field (coercive
magnetic force) so that it changes the orientation of the bits held on the media
(reducing magnetic flux density to zero).
