Question
The two identical bar magnets in Figure 23-11 are dropped from rest along a vertical line passing through the center of the rings, as shown. The two rings are identical in every respect except that the ring on the right has a small break in it. Calling aL and aR the magnitude of the downward accelerations of the magnets on the left and right, respectively, you observe that
A) aL = aR.
B) aL > aR.
C) aL < aR.
D) It is not possible to predict the outcome of this experiment with the data given. Answer: C
Explanation / Answer
C. aL < aR, because there is not any current is flowing through the right ring. The only acceleration will be due to gravity. which is downward. But in the left ring, there will be induced emf & current flow & a/c to Lenz's law, it will oppose the bars movement by magnetic field induced in it.
