Does your news provider give you alt.binaries.schematics.electronic?
If so, I'll post a formula (a complicated one) over there.
And, give me the details for a typical coil that you will wind; number of
turns, thickness of strip, width of strip, spacing (insulation thickness)
between turns, inner radius of coil, and outer radius of coil so I can work one
example for you.
