Hand-cranked AC alternator powers 120 volt lamp.

Hand-cranked alternator powers 120 volt lamp. This alternator consists of a cylindrical coil of wire that rotates within the stationary field of 5 permanent horse-shoe magnets. A geared hand-driven crank causes the coil to rotate. The rotating coil cuts across the magnetic flux of the horse-shoe magnets, inducing an emf. Depending on the speed that the generator is cranked, the AC voltage may be as high as 120 volts. The light bulb connected to the alternator glows brightly. NOTE: A larger, hand-cranked DC generator is also available (D+15+11). A projection voltmeter or ammeter may be introduced into the circuit if desired.
