OK
What if a hypothetical homebrewer needed to create a slugged coil inductor
for his homebrew receiver, and he wondered how many turns he would need to
create a nominal inductance of 4.5uH?
Suppose he found a ceramic form at Antique Electrical , a 1 5/8" size that
was just perfect? (copy this in your browser)

Where would that hypothetical homebrewer find how many windings he'd need?
Most of the formulae he (that hypothetical homebrewer) found was directed it
appeared to larger coils, like for crystal radio main coils.
Can anyone point that hypothetical homebrewer to the right formulae?
Thanks (on behalf of the hypothetical homebrewer)
