Today I found in my archived files an Excel sheet that
computes the number of turns for a given inductance
on a given core, and viceversa, made by WA1ION.

In my opinion it contained an error, as it used the same
formula involving AL, both with ferrite toroids and
iron-powder toroids. Amidon gives two different
formulas for the two cases. I corrected it, and added
a couple of other, maybe useful, functions.

If you want to check it, you can download it from here :

Please report any errors, thanks
