    How do you get the coil to keep spinning if you completely remove the enamel from both sides of the wire? I would think the coil's magnetic field would simply alight with that of the permanent magnet's and just sit there. In order to spin the current through the coil has to stop for at least half the cycle.

    Hey thanks loads for this!! It's just the kind of thing I'm looking for, for my ten yr old home schooled son : ) Many thanks for sharing!

    A 'Hard Disk' is a component from a computer it stores data. it consists of an electro magnet coil an arm and at least 1 platter which is a metal plate. this is done by useing magnets.

    I don't know about you, but I'm not planning on going where there's no gravity any time soon. ;-)

    Any photos or stills from the video? I am no a connection that can not view streaming video, not because of the lack of bandwidth but the fact that the service I have is so crap, most I get os about 108kbps average on a service they sell as T1 over 3G/HSDPA connections. So some stills would be nice to see.
