I have been trying to start doing projects with the kids each weekend. Last weekend we tried to make a simple speaker from scratch, no success on that one so far. So this weekend I went for something easier and we made a simple motor out of wire, paperclips, magnets, tape, an AA bettery and two alligator clips. All taped to a plastic plate base. Above is a picture of it unhooked (I used small ceramic magnets to hold the wires to the battery). The coil is about 35 wraps of 26 AWG enamel coated wire. The connections to the clips have the enamel scraped off one side, so each revolution the electromagnet turns on and off repelling it from the magnets below and it spins. Below is a picture in action.
T made a motor like this from a kit a few years ago, but this one is completely from common off the shelf parts.
