Yes as long as the wood is not to thick.
does magnetic forces pass through cardboard? <><><><> Very easily. Lay a paperclip on a sheet of cardboard. Place a magnet beneath the cardboard. When you move the magnet, the paperclip will also move.

The copper, technically, wouldn't increase it's power but rather extend the magnetic field of the magnet.
No, aluminum is not a magnetic material. But you could shape the aluminum foil into a coil, then pass a current through it and then it would be an electromagnet.
what are the things pass through magnet fields?
Yes heat can pass through wood.
Yes as long as the wood is not to thick.
yes
coz wood is an insulator, where there's no free electrons n thus current pass through the wood :)
yes
Yes!

A current would be induced in the coil.

after you get the magnet train pass use the magnet train
