real electric motors work
The infamous "ball bearing" motor
motor is nothing more than a shaft supported by two ball
bearings. Current is fed to the outside of one bearing,
runs through the shaft, and out the other bearing. It sometimes
needs a little kick to get it started, but once turning
will run equally well in either direction.
• Perfect conversation-starter at parties
• Creates confusion amongst engineers
• Completely useless
• Requires staggeringly high currents to make it turn
motor has no windings, brushes, magnets, and cannot possibly
work. Except that it does. Click here
