Lex talked about very small gauge magnet wire he used for an invisible antenna, and said he paid a dollar for that wire.
I don't know where to buy that kind of wire. It's easier to find it for free in discarded devices such as DC motors of cassette or CD players, or mechanical relays.
For stronger enamelled wire, that can be found in powerful AC motors. It's very uneasy to get the motor from a discarded washing machine on the curb. Rather, just load a discarded vacuum cleaner and disassemble it at home. The wire of the moving coils can't be removed without harm to it, but the wire of the static coils can be removed cleanly with some astuteness. Beware, some low grade vaccum cleaners are built with aluminium wire, that can't be uncoiled neatly. Remember to scrap the enamel on the tip of the copper wire for good contact, don't rely on soldering heat.
