...... .(55). T Magnetising Force (56). 198. Reluctance.—The magnetising force or magnetomotiveforce, as it is called, is the force set up by the ampere-turns,which drives the magnetic lines, or magnetic flux, through themagnetic circuit, just as an electromotive force causes a currentof… … ing force before induction is invoked. The number or densityof lines of force per square inch of the circuit is called theinduction per square inch and corresponds with the currentin an electric circuit. It depends upon the magnetisingforce and reluctance. The length ofthe magnetic circuit in Fig.…
