The University of Illinois paper I mentioned earlier was by Brooks.
Can't find my original but is there some other source? He was pushing
the possibility of air-core coils for 60 ~ power work, which of course
has never happened.
"Brooks, who wrote a paper in 1931, calculated that the ideal value for
the MEAN RADIUS is very close to 3c/2
where c is the sides of a square that revolves around a radius - eg a
in other words the middle of the square former is the radius 3c/2

|< 3c/2 >|
The shape is not absolutely critical as a fairly large % deviation from
this shape will still have a large inductance....
