As Terry mentioned, heating the end of the wire with a fine tip soldering iron and coating with solder should remove the insulating enamel. It will be very difficult to scrape it since the coil appears to be wound with Litz wire. Litz is composed of multiple strands of very fine enameled wire with an overwrap of silk or cotton. Try heating the ends until solder sticks to them and then join together. If you get continuity through the coil then all should be well.
