K4-01: AC/DC GENERATOR

ID Code: K4-01
Purpose: Demonstrate a simple AC/DC generator.
Description: The generator consists of a coil which rotates through an appropriately shaped magnet, which is powered by a 1.5 volt battery. Turning the crank generates either an AC voltage, using a double commutator, or DC voltage, using a split ring commutator. The commutator must be set manually for each case. The output is displayed by the meter. Shown in the photographs above are connections for AC (left) and DC (right) commutators. The button adjacent to the batteries must be held down to activate current in the magnet coil.
