Find the magnetic flux through the ring as a function of time. Part 2: Determine the induced current in the ring. Part 3: Calculate the time-averaged force between the magnet and the ring. Does the ring levitate? Part 4: New twist: Replace the superconductor with a perfect conductor. After $t=10$ seconds, the current reaches a steady state. Explain why.
