Yes induction works fine in copper. Copper plates work quite well for
magnetic braking etc. Take a medium sized NIB magnet that's a close fit, and
drop it down a thick walled copper or aluminum pipe and note how slowly it
falls. Something like iron that takes a weak field will probably be more
efficient at heating up but that won't stop copper from working as well just not
as fast.
I think the thinness of the copper will be the real problem, much of the
field may not be going through the copper. Really depends on frequency and a
few other factors, go high and it should become RF type heating if you can pump
it out.
I don't really see any advantage over a normal iron or other heater with it
though.
I have been looking at a flat pan or griddle type system. A low (for cooking
anyway) even heat, hold the paper and board above it to preheat the board, then
lower and press firmly into the surface to make the transfer. Should be notably
superior to either an iron or roll laminator. But I've got about ten other
projects ahead of it, and an iron works fine for the boards I make so this one
is low priority for me.
