he use of certain quantities whichdo not occur at all in direct current phenomena. Henceit will be well at the outset to gain some familiarity withthese terms. (a) If the magnetic field in which a closed coil ofwire revolves be uniform, the E.M.F. generated in thecoil will vary as the sine of the… … Fig. 22. sive points will be proportional to the sines of the corre-sponding angles through which the coil has turned fromthe position of zero E.M.F. The E.M.F. is zero when ALTERNATING CURRENTS. 23 I the plane of the loop is perpendicular to the lines ofmagnetic force. Fig. 22 shows the sine…
