remanence

[′rem·ə·nəns]
(electromagnetism)
The magnetic flux density that remains in a magnetic circuit after the removal of an applied magnetomotive force; if the magnetic circuit has an air gap, the remanence will be less than the residual flux density.

remanence

The persistence of residual magnetism (on magnetic storage media) or deformations (on optical media) that may carry information susceptible to discovery using special techniques. To avoid compromise of confidential information, one can destroy data by repeated overwriting with random data.
