Coaxing the coil

Take your ferrite rod, 26 gauge enamel-coated wire, some electrical tape, and glue and get ready to make the coil by following these steps:

1. Wrap electrical tape around the ferrite rod. This protects the enamel coating on the wire from the ridges that run along the rod.

2. Cut two small pieces of electrical tape, about 14" wide, and place them in a handy spot.

3. Leaving about 8 inches of wire loose, start winding the enamel-coated wire around the rod, starting about 114" from one end.

4. When you have about 20 turns of wire on the rod, secure that end with one of the pieces of electrical tape so that it doesn’t loosen while you are finishing the coil.

5. Wind a total of 50 turns of wire around the rod, leaving another 8- inch length of wire loose at the other end.

6. Secure the wire at that end with the other piece of electrical tape.

7. At each end of the coil, use some glue to hold down the wires.

 

We had you cut the electrical tape 14" wide so there is enough exposed wire to glue. When the glue is dry, your coil is finished. The finished coil is shown in Figure 8-13.
