Description
The AC/DC generator is used in reverse as a motor. A 7.5 volt battery is connected across the rotating coil through the split-ring commutator, the 1.5 volt battery is connected to the permanent magnet by pressing a switch on the chassis, and the coil is given a bit of a push to start it rotating. NOTE: Please disconnect the 7.5 volt battery when not operating the motor so that the coil will not be destroyed.
