10 RICHARDSON'S BLUEBOOK OF PROJECTION employed for storage of power generated by the first named method. How a Generator Armature Acts (22) The generator depends for its action primarily upon the following law: "If an electric conductor in the form of a closed circuit be moved in a magnetic held in such manner that the said conductor will cut (pass through or across) a variable number of lines of magnetic force, a voltage will be built up and a current of electricity caused to flow in a direction at right angles to the line of motion of the conductor/' Figure 1 Figure 1 is the diagrammatic representation of a dynamo in its simplest possible form. (23) We»*a permanent magnet between the poles (N and b) o which flow lines of magnetic force represented by dotted lines. This flow constitutes what is known as magnetic field Within this "field" is copper wire AB, bent into the form shown, which represents the armature of a generator. One end of this wire is attached to flat-faced metal ring C ; the opposite end to a similar ring, V. _ Bearing upon the end of each of these rings and in electrical Contact therewith are "brushes" K and J, to which circuit wires E and F (positive and negative
