Breakers off, but still 6v?

math

it's got an "s" on the end in this country.

Whats a math?

inductive coupling is dominant at low frequency

You might want to re-think that.......

Taken from Wiki (but also from my degree notes)

"Inductive coupling favors low frequency energy sources. High frequency energy sources generally use capacitive coupling."

You don't see linesmen worrying about capacative coupling either...

don't worry about it. Digital meters have such a high impedence that they will show all sorts of wierd voltages. If you were to put a load across it, say a 6v lamp, the light probably won't illuminate as the voltage will just be dragged to zero volts.

I don't agree with this statement.For a given number of turns, at a given current the only way to increase voltage induced, whether it be self or mutual, is to increase the frequency (ie rate at which the magnetic flux is cutting the conductor)
Therefore it follows that maximum inductive coupling (ie greatest voltage induced) occurs at higher frequency.
This being said the inductor will display a higher impedance (if a current were to flow) at higher frequencies.
