etic circuits inelectrical machinery are of this kind.It should also be noted that the mag-netic circuit is quite analogous to anelectric circuit in that the introductionof resistance diminishes the magneticflux. There is, however, this difference :the introduction of an air gap into the ordinary… … Fig. 64. — Iron ring with airgap in magnetic circuit. ELECTROMAGNETISM 107 77. Magnetomotive force. We have already said that themagnetizing force of a solenoid or any coil of wire depends uponthe turns of wire as well as upon the intensity of the current.That is, magnetizing force is proportional…
