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.
You can’t just memorize "( T = 2\pi \sqrt\fracL\cos\thetag )." You have to rebuild mechanics from scratch. russian physics olympiad problems pdf new
