Step 3: Finish the Voice Coil
Remove the magnet and glue the paper coil in the direct center of the bottom of the paper plate. Remove the inside coil of paper. Re-insert the magnet. Using the magnet wire, start making turns, about 50-60.
TIP: Tape down the first piece so it holds as you wrap.
Try to wrap it tight. Then tape the final result securely with scotch tape. Remove the magnet.
TIP: You can use a multi-meter to check the ohms. You want to get as close to 8 ohms as possible. You must remove the enamel off the ends of the wire to make contact and the easiest way to do that is to burn it off with a lighter.
