The south pole of a bar magnet is moved toward an aluminum ring, along the axis of the ring. As the magnet approaches, the changing magnetic flux induces an electric current in the ring that, when seen from the bar magnet, corresponds to positive charge carriers flowing

Question

According to Lenz's Law, the induced current will flow in a direction that opposes the change in magnetic flux. As the south pole of the magnet approaches, the ring will induce a current that creates its own south pole facing the approaching magnet, resulting in a clockwise current when viewed from the magnet's perspective.
