1. A constantalternating current is supplied to the stationary primary coilwhich induces a current in the movable secondary coil. Thepressure induced in the coil will depend on the number of linesof flux which pass through it and by changing its position inthe magnetic field over the primary a… … ALTERNATOR Fig. 1,981.—Elementary diagram illustrating the principles of constant current transformetas used for series arc lighting. Since the induced currents in the secondary are repelled bythe primary there is a tendency for the secondary coil to jumpout of the primary field, and in case of a…
