Step 2: Wrap it up!! (not really)

Now you need to start putting the electromagnetic wire into coils. You need some left over wire so you can solder it onto more wire (like 5 inches).

It's both, the core of the wire is just regular copper wire but it has a enamel on it that electrically insulates it from the other wires so that it doesn't short out.
