Definition of "magnetomotive force (MMF)" |
(1) a magnetic circuit term referring to that phenomenon that pushes magnetic flux through the reluctance of the circuit path. MMF is analogous to the concept of electromotive force (voltage) in an electric circuit. For a magnetic core with a single coil ofN turns, carrying current I , the MMF is NI, with units of amperes (sometimes expressed as ampere-turns). |
