SpletThis relationship is called Magneto Motive Force or m.m.f. and is defined as: ... Thus we believe covering a wound coil with a diamagnetic material would have little or no effect on the magnetomotive force strength of the magnetic field in the centre of the coil of wire. More current flow in the turns of the coil, the stronger the magnetic field. SpletIn short, a force which is responsible to drive flux in the magnetic circuit (same as electromotive (EMF) which drives electron in an electric circuit) is known as magnetomotive force . The SI unit of MMF is AT (Ampere-Turns) and G (Gilbert) is the CGS unit of magnetomotive force. It is also known as Ohm’s law for magnetic circuits which can ...
