t passes from onepole to the other. By this means the current in the external The Dynamo 1035 circuit is kept constant in direction^ although it alternatesin the armature. The faster we turn the wire or armature^ the greaterwill be the electro-motive force generated. Instead ofusing only one wire^… … Fig. 427 Here we have many wires cutting the lines of force at onceand the electro-motive force with the same number of rev-olutions of the armature is correspondingly increased, andthe more turns of wire we arrange to cut those lines of forceper second the greater will be the E.
