toroid transformer Q

No, you're fine. The nifty thing about toroids id all of the flux stays in the
core or very near to it. The flux in the center of the hole is zero. Toroids get
mounted this way all the time.

Hi all,

A thought suddenly struck me: I have mounted a 15 VA toroid transformer inside
an aluminum enclosure by means of a screw through the hole. But this screw is
in contact with the enclosure at both ends, actually. So isn't this then 
actually a winding, which is shorted?? 
Is this bad? It has worked fine so far. The aluminum enclosure is just a little
bigger than the toroid itself. It doesn't get hot, nor does it make funny
noises.

Thoughts?

Thanks,
Hallgeir
