Faraday Motor - can you help?
Am looking for a bit of advice on this one - has anyone built a Faraday motor? I knocked this one up a while ago now just to try the principle but it never really worked properly. Basically, DC current is fed to the hook at the top of the stick which then feeds down through the dangling rod into the dish, which is full of a conductive liquid (Mercury in the original - but I'm using salt water). The circuit is completed by another wire leading out of the conductive liquid to the other side of the power source. A magnet is placed in the center of the dish and the dangling rod is supposed to spin around it.
