How to Make Something Spin Without a Motor

Whether you need to make something spin without a motor or just want to show off your engineering skills, this article should help. It's not perpetual motion or "over-unity"—that's a whole other level of complexity—but it's a cool generator/motor project that will impress friends and coworkers. You can find more details about [lasersaber]'s EZ Spin motor on his site and this forum post, or check out a 3D model on Thingiverse.

Place one neodymium magnet on the top of each battery, and set the coil of paper clip loops—which you've made into the "armature" of the motor—on each magnet, with the shiny side of the clips touching the magnets. Then, give the armature a push in the direction you want it to spin. Current flows through the closed circuit and generates magnetic force to rotate the coil.
