Explain how an electric motor works. ... Build small electric motors using inexpensive materials. Try to make modifications in the design to produce the greatest amount of spin on the rotor, or the greatest torque on the shaft. The diagram below illustrates a simple set-up that does not require any elaborate equipment.
