DEMONSTRATION DYNAMO MOTOR
 
DEMONSTRATION DYNAMO MOTOR (1719)
A versatile model to demonstrate the working of both dynamo and motor. Driven with a rubber belt on a hand wheel a two pole armature rotates in a magnetic field provided by a permanent magnet. The D.C. current thus produced glows a torch lamp at two 4mm sockets. To demonstrate the apparatus as a motor the belt is taken off and a DC current of 4 to 6 volts is applied at two 4mm sockets which sets the armature is motion. All fitted on wooden base.
