and the flux <f> nowpasses from b to a and therefore passes through coil C in the oppo-site direction. A high peak of e.m.f. is obtained from such machines by shapingthe pole faces of the revolving parts so that the flux threading thecoil C changes as shown in curve a, Fig. 279; the flux… … Fig. 278. —Magneto alter-nator.

The current lags the voltage by an angle awhich increases as the reactance of the circuit increases and there-fore increases with the frequency of the alternator or the speed ofthe…
