Introduction: These Hearts Are on Fire
The homopolar motor is the simplest motor in the world. It's made of a battery, magnet, and a piece of wire.
In this case, I use a AA size NiMH battery, a 1/2 inch x 1 inch neodymium supermagnet, and some bare 10 ga. copper wire. I bent the wire around a D-cell battery to form the heart shape.
This video shows several variations of this motor, using two different wire-form heart shapes as the basis. In the end the two hearts unite to become one.
