___By converter I refer to the little transformers you plug in the wall to power radios, tape recorders, etc. A little plastic box that plugs right to the wall & has a low voltage DC cord coming out. You can pick up old ones at Goodwill or such sort of used stuff store.
___Breaking open the plastic box one finds a transformer inside with two coils of coated copper wire. (Now it gets a little harder, so if you can just go buy some similar thin wire)
In order to get the wire you have to free the coils from the metal plates that form the transformer core. While the plates appear solid, each layer is 2 pieces, one fork shaped (which pokes through the coils) & a flat bar shape (which caps the forks) Which a small prying tool, break the glue bond & spread the plates to release them one at a time. The forked plated point first one way through the coils then the other.
___ If you get through that, you now have two nice coils of wire, one heavier guage than the other. For your experiment, the thinnest wire seems the better choice.
___A multimeter is a small electrical testing device available in most electrical or automotive department stores. An inexpensive one may only cost $10- $15 dollars. It will measure AC & DC voltage (you want the DC setting), as well as resistence & low amperage. Typically it has a simple dial marked with different scales;if the needle moves you have current & how far it moves is a measure of amount.
___Hope this helps more than confuses.
