ints in the direction of motion of the movingwire and the first finger in the direction of the linesof force, or from the north to the south pole of themagnet, the third finger will point in the direction ofthe flow of the induced current. If the bar in Figure 22 is moved slowly the E.M.F.generated… … 1 1 Figure 22 Figure 23 will vary directly as the lines of force vary. We cantherefore raise or lower the E.M.F. of any dynamo byvarying either the speed of the moving conductors orthe intensity of the magnetization of the fields or byboth. An E.M.F. of one volt is obtained for every 100,-000,000…
