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.

Strictly speaking, the multispecimen method should not be applied to multicomponent remanences, so that the results should be discarded.
Stepwise alternating field demagnetisation of NRM identified a single, stable characteristic remanence component with very well defined directions at both a specimen and structure level.
Our text interrupts, cites, and enfolds others, to allow intertextual vectors to emerge and discursive remanences in the archive to come to light.
