Inductive Coupling through a Steel Enclosure

If holes are being cut in the steel for cores, can you pass light
between the two boxes? Like a bright globe or LED and a solar panel on
the other side, this will give you a few watts out of 100.

5 mm is an exceptionally long distance for even an unshielded inductive
coupling. Especially if large amounts of energy are to be efficienty
transferred.

This is called the "electric toothbrush problem" and it has yet to be
satisfactorily solved.

I once made a battery charger that would charge across an airgap of
around 3cm using resonant LC on each end.
Not particularly high power, but not wildly inefficient either.
