This has got to be the world’s simplest electric motor. You can do it yourself, should be quite safe I think.

nice, simple experiment
By your_angel 1167647657 Reply Spam [+2] Moderate Up Moderate Down RemoveIt have to be a copper wire?
It wont work for me somehow.
Very nice experiment 5 stars for me
By Teddy28 1167736502 Reply Spam [+1] Moderate Up Moderate Down Removeit shouldn't accelerate indefinitly cose but untile the current gets the max amperage
it just uses the Lenz and Maxwell formulas
Nice work.
By samlaunch 1170986449 Reply Spam [+0] Moderate Up Moderate Down Removewhere can I get a electricity conductive magnet?
The battery +/- are from aluminium. How does the magnet attract the - pole of battery???

i need this to show my friends its awesome
ill tell them all to get metacafe
There are 4 components, from the top to the bottom:
Electrical wire
Size AA Battery
Sheet metal or wood screw (needs to be magnetic/ ferrous)
A round, flat magnet (the thing at the bottom)
How it works:
The battery has a pos and negative side, the same as the magnet. When the magnet is attached to the (ferrous) screw, and then stuck (magnetized) to the bottom of the battery, there is an exchange of charges (although very minor). When the wire is run from the top of the battery to the side of the magnet, it causes current to flow, which causes the magnetic field around the magnet to expand, which pulls harder on the wire, causing the magnet to spin faster.
Eventually, as you saw, the magnet will spin so fast that it destabalized the screw, which broke the connection between the battery and the magnet.
What you see here is one of the basic principles that drives "Bullet" trains and superconductors.
