wrould have to cut 42 Operating and Testing through this field 50 times per second to generate anE.M.F. of one volt. The generation of E.M.F. in this way is known aselectro-magnetic induction. Figure 24 represents a coil of wire the ends ofwhich are connected to the two collector rings 1 and2.… … Figure 24 magnetic field, it would generate a current whichwould manifest itself in the outer wires C, either byheating them or by its effect upon instruments wemay place in the circuit. We can get a clearer ideaof the nature of this current and the laws governingit by reference to Figure 25 which…
