Eddy Current Tubes — Drop the Magnets down the tube. An eddy current is set up in a conductor in response to a changing magnetic field. Lenz’s law predicts that the current moves in such a way as to create a magnetic field opposing the change; to do this in a conductor, electrons swirl in a plane perpendicular to the changing magnetic field. Because the magnetic fields of the eddy currents oppose the magnetic field of the falling magnet; there is attraction between the two fields. Energy is

Is this the solution to the crisis?

The law of conservation of energy forbids perpetual motion of this type. On the other hand, the small magnets in this image seem to be attracted / repelled by the large magnet, producing motion. What’s actually going on here?
