What reading level is Electric Railway Motors Their Construction Operation And Maintenance An Eleme book?
To quickly assess the difficulty of the text, read a short excerpt:
If a coil of one turn of wire such as has been discussed heretofore revolving in a given magnetic field at a certain speed generates an electromotive force of say one volt, a coil of two turns or a coil of three turns revolving at the same speed in the same field will generate an electro- INCREASE OF ELECTROMOTIVE FORCE. 91 motive force of double or treble as much. That is to say that since a given current passing two and three times around a bar of iron or space will generate two and three tim...es as many lines of force as it will if it passes around but once, so if a coil of one turn cutting the lines of force at -a given rate generates a certain electromotive force, the same wire bent into a coil of two and three turns will under like conditions generate two and FIG. 29.
three times as many volts. Thus if a coil such as is represented in Fig. 31 (seepage 93) be substituted for the coils of a single turn represented in the previous illustrations, it will at the same speed of revolution generate twice as much electromotive force, because in doubling the wire it is equivalent to doubling the rate at which that wire cuts the lines of force which alone determines the electromo- tive force that will result.
