Main Question or Discussion Point

I am making an inductor coil out of wire that I removed from a piece of insulated copper wire. The inductor didn't conduct and I checked the conductivity of the coil alone via a multimeter and it didn't conduct any electricity and it is a copper wire so I need to know what is going on here! Thank you!

My first guess would be that there is an insulating coating on the wire. Try to sand it a bit. If the color changes to a bright copper, then there is a coating.
