1. Cut a 2.1 meter length of 11 gauge, solid core magnet wire.
2. Wrap all of the 11 gauge wire around a 4 inch length of 11/4 inch diameter dowel rod. The coils should be packed as closely together as possible and wound as tightly around the dowel as possible.
3. Once all of the wire has been wrapped around the dowel, it is helpful to tap the ends of the wire with a rubber mallet so that they follow the curve of the dowel.
4. The coil is now complete. Remove it from the dowel and set the coil aside for now.
