Magnetomotive force (MMF) or magnetomotance (SI Unit: Ampere) is any physical driving (motive) force that produces magnetic flux. In this context, the expression "driving force" is used in a general sense of "work potential", and is analogous, but distinct from force measured in newtons. Magnetomotive force is so named because it plays a role in magnetic circuits analogous to that of electromotive force (voltage) in electric circuits.

Famous quotes containing the word force:
“We should have an army so organized and so officered as to be capable in time of emergency, in cooperation with the National Militia, and under the provision of a proper national volunteer law, rapidly to expand into a force sufficient to resist all probable invasion from abroad and to furnish a respectable expeditionary force if necessary in the maintenance of our traditional American policy which bears the name of President Monroe.”
—William Howard Taft (1857–1930)
