Question
The figure below shows three situations of conducting loops in magnetic fields. The loop is in the plane of the paper and the direction of the magnetic field is given by the direction of the arrows. The arrangements change from the initial-state (i) to the final state (f) for each diagram. Select True or False for all statements. In diagram A, while changing from (i) to (f), a clockwise current is induced in the loop. In diagram B, while changing from (i) to (f), a counterclockwise current is induced in the loop. In diagram C, while changing from (i) to (f), a clockwise current is induced in the loop.Explanation / Answer
1) false:Since the area is decreasing , the flux is decreasing, so the current has to produce a magnetic field to oppose the change which would be a counter clockwise current
2) true
3) flux does not pass through the loop so no current is produce
