Simple Homopolar Electric Motor





Introduction: Simple Homopolar Electric Motor

Here's a video I made a while back. It has had some pretty amazing popularity around the web and I thought I might as well include it here. It is not unique, but hopefully the video is helpful to some of you.

    i tried this thing but it dose not won't to work!!!!!!!!!!!!!!!

    Did u get a neo magnet, copper wire, and a fully charged battery

    .....can you please give me a website that I can Buy a Magnets - neodymium magnets round

    There is no explination as to how this works. It is actually a small phenomenon


    It is a phenomenon, though not so small in my opinion. Any way the motor works just fine and fancy it is.
    Phenomena of this kind have been described by physicists and electrical engineers for some decades. One wikipedia entry could be Force on a current-carrying wire . The formula which describes the force in case of a straight, stationary wire shows that the force is proportional, among other factors, to the current. In this case the current is significant, since it is a short-circuit current. This example of electrical engine is cute and fancy. Watching the video was great fun.
    In the pictures below I tried to draw the model and the circuit.

    Can you use any kind of wire that is atracted to magnets?

    No, use copper wire (not ferromagnetic) and a neodynium magnet with the silver metallic coating. The magnet has to be conductive and the wire has to NOT be attracted to a magnet.
