A conducting ring falling toward the north pole of a bar magnet.
A conducting ring falling toward the north pole of a bar magnet.
A horizontal circular conducting ring with electrical resistance \(R\) is dropped from rest from a position above the north pole of a fixed vertical bar magnet. As the ring falls toward the magnet, an upward magnetic force acts on the ring, causing its downward acceleration to be less than \(g\). Which of the following statements correctly identifies the direction of the induced current in the ring (as viewed from above) and provides the correct energy conservation explanation for this system?
