Do you have a homemade generator wire?
The battery can be used as a diagram, one end of which is connected with the middle part of the copper wire, and the other end is connected with the middle part of the copper wire, and the non conducting electricity is the enameled wire. (simple test, the weak current is good, and the strong electric motor can cause electric shock risk)
Must paint the package, or if the short circuit between the line and the line, the number of turns you around the equivalent of around 1 times. As long as the surface line and line contact without electricity.
It must be insulated and not long enough to connect, but make sure that it is insulated. It seems that you can just generate electricity, so how many laps can you do?. I have some enameled wires on my hands. I'll make one, too
