- Leaving about 8 inches of wire loose, start winding the enamel-coated
wire around the rod, starting about 1^1 ⁄ 4 " from one end. - 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. - Wind a total of 50 turns of wire around the rod, leaving another 8-
inch length of wire loose at the other end. - Secure the wire at that end with the other piece of electrical tape.
- At each end of the coil, use some glue to hold down the wires.
We had you cut the electrical tape^1 ⁄ 4 " 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.
