Re: Toroid winding numbers and measurements
PeterYes, a scientific fact.Does this "fact" only apply for iron dust cored inductors because the
So do iron dust cored inductors include a frequency term?
If so just how much difference?
My tests on air and ferrite cored coils have been with this https://sites.google.com/site/vk3bhr/home/lcm1 and using 1% capacitors to make these coils resonant at around working frequency and careful GDO measurements.
People quote that frequency makes a difference, say it's a fact but then do not seem to be able to give examples of when any differences become significant, say more than a few per cent.
