This Valentine instructable shows a pair of Hearts that unite to become one! The homopolar motor is the simplest form of electric motor, consisting of a battery, a conductor, and a magnetic field. The flat Heart shape is the most basic of homopolar motors. The Heart with legs is the next most simple shape. With a little ingenuity, the two shapes can be combined to unite into one spinning body. In this Instructable, I show how to make this special 2-piece homopolar motor with a bass speaker, some coins, a battery and two pieces of copper wire. A neodymium magnet can also be used instead of the bass speaker and coins. This is a great display for Valentines Day…or any day of the year!
