- FIG. 1.—If a current of electricity is passed through a wire, the wire will attract to itself iron filings.
- FIG. 2.—If a wire carrying a current of electricity is formed into a loop, the space enclosed by the loop will become magnetic. The arrows represent the paths of the lines of magnetic force.
- FIG. 3.—By forming the wire into several loops or a spiral so that the effect of the individual turns is concentrated in a small space, an Electromagnet is made.
- FIG 4—The strength of an electromagnet is proportional to the ampere turns. The magnet illustrated above does not possess sufficient turns to be very strong.
- FIG. 5.—An increase in the number of turns of wire has resulted in considerable increase in the magnetism and this magnet is able to lift a much greater weight than that shown in Figure 4.
- FIG. 6.—The Principle of the Electric Motor.
- FIG. 7.—Diagrams showing the difference between a Shunt and a Series Motor.
- FIG. 8.—Details of the Armature for the Simplex Two-pole Motor.
