Instructions
To create a generator, the top two commutators must be in contact. An attenuator is connected to the Cenco generator, then also connected to a galvanometer. The upper commutator is a pair of cylinders connected to each end of the coil; if the projection galvanometer is connected to these terminals, it shows the AC output that is expected. Two magnets must be placed on the outside of the solenoids, opposite poles.

To operate, spin central solenoids with hand to see current readings off of the galvanometer.
