Re: Iron transformer positioning under the primary experiment

I put a piece of copper under the primary like this:
It hardly made any difference!!! The magnetic fields around the
primary must stay very close the the coil!! I don't know if there
are any magnetic field mapping programs out there that could show this?
But it appears you can put metal objects really near the primary!!
Your copper sheets will have high conductivity and low loss even
though they are coupling to the primary enough to reduce the
inductance. I would think they would also provide eddy-current
shielding of a transformer immediately below.
