Magnetomotive force (mmf) is the cause of the existence of a magnetic flux in a magnetic circuit, mmf,Fm = NI amperes where N is the number of conductors (or turns) and I is the current in amperes. The unit of mmf is sometimes expressed as ‘ampere-turns’. However since ‘turns’ have no dimensions, the SI unit of mmf is the
