What makes this work upside down?FT. -
Faraday's and Lenz's laws apply.
Same as the science class eddy-current demo where a magnet falls down or slides along a non-magnetic conductor very slowly due to induced currents creating magnetic fields which interact, but with a resistivity of zero instead of falling slowly it doesn't fall at all. Probably a type II superconductor; higher transition temperature = stronger currents = stronger fields = it 'sticks' upside-down.
