I could not get the math to work out without changing the formula. Take the
popular 3-core transformer (BN-73-202) with 2 turns:4 turns. This is
supposedly a 16:1 transformer. In order to do that, the turns have to be to
the 4th power, and not squared. If you just square the turns, you get a
4:1 transformation.
