A simpler DC motor
A few years ago Alan, VK2ZAY, showed Billy and me how to make a very simple DC motor. This one looks even simpler. I'm guessing that the bottom of the coil is making intermittent contact, setting up flux lines that get torqued by the magnets' field.

It's a Faraday motor! Faraday's original motor was a bit different because he didn't have access to small batteries. He also used a jar of mercury as a conductive material (though I think salt water can be substituted). A quite attractive looking recreation: http://www.dailymotion.com/video/xek6ka_james-dyson-demonstrates-michael-fa_tech
