It’s great, but hardly unexplained! It spins because of the magnetic field created by the electricity in the wire.
it works because theres uh nigger in there spinnin it
When you create a circuit through the wire, the moving electrons also create a magnetic field around the wire. This field is reacting to the magnet on the bottom to push the wire around.
Wow….That is _NOT_ an unexplained phenomenon, that is, you know, how an electric motor works. The battery puts a current thought the wire, which is attracted to one pole of the magnet, it swings around but it goes too far and then gets repelled by the other side. Having trouble grasping that very simple concept? http://electronics.howstuffworks.com/motor1.htm
it’s simple actually….a moving charge (current) in a magnetic field has a force imposed upon it (i think it is the lorrentz force) orthoganal to both the field and the current direction…you can also make a rail gun this way…=)

sorry lorentz force…

fun project!
Electrical current creates a magnetic field (left hand rule). My guess is that the magnetic field created by the wire repels the magnet’s field. They’re trying to push each other away, but the wire is wrapped around the battery so it just goes in circles. I’d be curious to see if turning the magnet over changes the direction of the rotation. Cool experiment. Thanks.
ripped off of an older science blog. The other guy got it to spin faster too.
Very simply it’s the flow of electrons through the magnets field causing the force which makes the wire rotate.
