   Also found in: Dictionary/thesaurus, Legal, Wikipedia 0.01 sec.
remanence

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.
