remanence

noun Electricity.

1. the magnetic flux that remains in a magnetic circuit after an applied magnetomotive force has been removed.

noun

1. physics the ability of a material to retain magnetization, equal to the magnetic flux density of the material after the removal of the magnetizing fieldAlso called: retentivity

n.

1660s, “that which remains,” from remanent + -ence. Meaning “continuance, permanence” is from 1810.

1. The magnetic flux density remaining in a material, especially a ferromagnetic material, after removal of the magnetizing field. Good permanent magnets have a high degree of remanence. Remanence is measured in teslas. Also called retentivity Compare coercivity.
