Hi Sykavy,

The enamel coated magnet wire is copper wire with a transparent coating of enamel. It comes in different thicknesses measured in guage like 23, 26, etc... the lower the number the fatter it is. The wire isn't magnetic but when wound into a coil and power is applied, it will turn into an electromagnet. The wire is insulated with the enamel so the wire dosn't short itself.

You want enough wire to wind 600 turns of both wires at the same time. 100-200 feet of each should be enough. Just wind the coil so that it fills out to the spool ends. Follow the dimensions of the coil in John's drawings. 100-200 feet doesn't cost that much and you can get at most electronic supply places in most towns. I buy wire by weight like 10 pound spools of whatever gauge...That is a lot more than you need, but shop around.




A couple of questions what is enough wire?
and
What is Enamel coates magnetic wire? Is the wire magnetic?
