Question

D3 MAGNETISM D3-RT43: WIRE LOOPS AND MOVING MAGNETS-LOOP MOTION In each case, a permanent magnet is moving toward a circular wire loop that is fixed in place. All of the wire loops are identical, but the wire in Case D has a small gap. The magnets are all identical, but they are approaching the loops at different speeds and with different poles facing the loops. At the instant shown, all of the magnets are the same distance from the wire loops. v= 4 m/s v=5m/s v=2m/s 5mis Small gap Rank the magnitude of the repulsive force on the loop by the approaching magnet at the instant shown. OR 4 Least All the same zero determine All Cannot Greatest Explain your reasoning.

Explanation / Answer

Greater the relative motion more will be the repulsion force so

B will be greatest and D will be zero since loop is broken so induced current will not flow.

So B > A > C > D
