Electric Motor Exhibition by Hands On!

Electric Motor

Visitors explore the behavior of both permanent magnets and electromagnets and their connection to electricity in this exciting, challenging exhibit. The motor consists of a 3-spoked rotor with permanent magnets affixed to the ends. The rotor is suspended from a horizontal shaft at the center of a transparent circular vitrine equipped with three electromagnets evenly spaced around its perimeter. When the visitor presses a brightly colored button, the electromagnets are activated. The fields produced by the electromagnets push the permanent magnets located at the ends of the spokes, causing them to swing away in a graceful arc. With proper timing of the electromagnets, the visitor can push the rotor in complete circles, creating an example of a simple electric motor.
