HAWKINS ELECTRICITY in Dynamos.—The field magnets of a dynamo increasestrength as the current which passes around them increases. Moreover, as the magnetic strength increases, the voltage ofthe generated current also becomes stronger. Hence, it is evi-dent that a dynamo is not self-regulating, and… … SWITCH ^^-^^IGNITION WIRES Fig. 3,952.—Motsinger Auto Sparker friction drive dynamo. The small friction pulley-gives sufficient speed to ignite the charge when engine is turned slowly as in cranking.After the engine is under motion, the governor on the shaft of the dynamo limitsits speed,so as not…
