Magnetomotive Force (MMF)

The term magnetomotive force was designed to talk about the use of magnetic flux in magnetic circuits. Visuals and equations feature MMF, typically measured in “ampere-turns” which consist of a single amp conveyed in a single-turn loop in a vacuum. Scientists may also use other nomenclature such as a “gilbert” (G) to observe MMF.

As a component of magnetic circuit analysis, MMF may be used wherever magnetic circuit technologies are designed, such as in sound technology.
