To determine
The direction of the induced current in the ring.

Answer to Problem 1FTD

The direction of the induced current in the ring is shown in Figure 1.

Explanation of Solution

According to the Lenz’s law, the induced current in the ring will produce a magnetic field, which will oppose the change in flux in the ring. Since the south pole of the bar magnet is pushed towards the conducting ring, the ring will produce a magnetic field, which opposes the change in flux due to the magnet. Thus by applying the right-hand rule gives the direction of current flow through the ring as shown in Figure 1.

Conclusion:

Therefore, the direction of the induced current in the ring is shown in Figure 1.
