i need magnetic wire to make a coil and build aradio
You can often get varnished wire at an outlet such as radio shack. I have also used the yokes of old TV sets that I usually got for free at a local repair shop. I had to carefully unwind the coils. The wire in an automobile ignition coil is another potentially free source. You can purchase electrical insulating varnish as well. Krylon makes an aerosol variety and most others come in a regular can, but you would have to be creative in dipping the wire and suspending it to dry without damaging the coating.
