Author: E.E. Kimberly

If a unit magnetic pole be placed in the magnetic circuit of Fig. 7-2 and be carried along the complete path of a magnetic line of force, the work done will be the magnetomotive force of the coil. Its symbol is M or mmf. In equation (7-5) the term


is the magnetomotive force, upon which the flux density depends directly.
