Re: Primary calculations

Hi Ed,

	Nagaoka's formula should work. A good reference, if you can find it
, for this is "Inductance Calculations" by F.W. Grover (1946). Nagaoka's 
Formula, however, requires the evaluation of some nasty integrals - 
fortunately, Grover has done this for us in a series of tables. If you can 
tell me roughly the height of the coil you're interested in, I could copy 
out the relevant parts of the tabl Grover also has corrections for cospace 
wound coils which sounds relevant in your case.
