Which of the following generates coercive magnetic force for the purpose of reducing magnetic flux density to zero on storage media?
A.
A magnetic field
B.
A degausser
C.
Magnetic remanence
D.
Magnetic saturation
Explanation:
A degausser is an electrical device (AC or DC) that can generate
coercive magnetic force for the purpose of reducing magnetic flux density to zero on
storage media or other magnetic media.
