e acts exactlylike a primary battery, such as is described in Chapter I. In short, if a wire is to have an e.m.f. induced in it, it mustmove so as to cut lines of force. Furthermore, it will be seenthat the direction of the induced e.m.f. depends upon twofactors, (a) the direction of the motion of… … Fig. 85. — Right-hand rulefor induced e.m.f. Flemings Rule. Extend the thumb, forefinger, and centerfinger of the right hand so as to form right angles with each other.If the thumb points in the direction ofthe motion of the wire, and the forefingerin the direction of the magnetic flux, thecenter…
