Magnetomotive force (mmf) is a quantity that appears in the equation for the magnetic flux in a magnetic circuit, Hopkinsons law. It is the property of certain substances or phenomena that give rise to magnetic fields. The SI unit of mmf is the ampere, which is the same as the unit of current. However, the unit name in the MKS system is the ampere-turn to avoid confusion with current. Occasionally, the cgs system unit of the gilbert may also be encountered.
