The optimum inductance for a given length of wire will be obtained when the
average radius is 4/3 of the width. The width of the winding will be 6.349"
and the average radius will be 8.5". Total number of turns will be 315.9.
The total diameter of the coil will be 23.3". The radius of the coil center
will be 5.291".
