How to Build an Electromagnetic Levitation Device

Need to take some weight off? With some circuitry know-how, a magnet, and a Hall Effect sensor you can build you own electromagnetic levitation device

"Do not levitate the spoon; that's impossible. Instead, only try to realize the truth. There is no spoon." - para. The Matrix (1999)

But what if there is a spoon? Or some other object. You can't just rely on the power of your mind to levitate objects. This project from Drew Paul of Drew Paul Designs is a DIY electromagnetic levitation device that can lift a small metal object into the air. Use it for a centerpiece at your next dinner party...or trick your friends into thinking you have magical powers. Just remember the old saying, the only difference between a magician and an engineer is the engineer will tell you how it's done.

Watch the electromagnetic levitation device in action.
