Magnetomotive Force

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.
