    Thanks for the post! Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post?

    The aluminum foil rises because the induced current and magnetic field are in the same direction as the larger ring. This means they are attracted because their magnetic fields align. However, the resistance is high enough that it is not repulsed by the coil when it is on there alone.
