This instrument can show effect of voltage and magnetism on the operation of a DC motor, runs on 3-6 volts DC. Includes motor components, permanent magnets, connecting wires, assembly instructions, should include replacement parts of 5 pieces belt and 2 pairs extra magnets.
Conversely can function as generator when the motor is cranked. Can clearly show difference between AC and DC generator, with AC & DC output terminals for measurement of AC and DC voltages.
