Get the Shirts: http://bit.ly/scishirts Mess with me on Facebook: http://facebook.com/dylanhacker The big question is: How does this work? The electrical current is traveling through battery, into the screw and wire in a normal fashion. But when then current hits the magnet, the electrical current is pulled out in a radial fashion instead of going straight through. Because the magnet has the ability to move. It spins as the current travels through it.
