Re: transferring electrical energy through metal wall

I'm not an expert on electromagnetism, but if I remember correctly this
metal box acts like Faraday's box.

If that's allowed, you don't need such sophisticated methods. Maybe you
could even consider just connecting the coils with a cable, which should
give you the maximum efficiency, as no energy conversions are needed.
