To make this simple homopolar motor you need a strong neodymium magnet, a coil made from bare copper wire and a 1.5-volt battery. The coil is shaped from BARE copper wire with no insulation. First you stick the strong magnet to the button on the battery. Then place the loop of the coil in the cylindrical magnet. Now as soon as you give the coil a little jerk it will keep spinning magically.

Now fix the coil with tape in a Styrofoam cup cut in half. This will make the model much more interesting. Now the half cup will rotate along with the coil. You can stick color tapes to the cup to make look very attractive. This work was supported by IUCAA and Tata Trust.
