Question

A metal ring is dropped into a localized region of constant magnetic field, as indicated in the figure(Figure 1). The magnetic field is zero above and below the region where it is finite. Choose the best explanation from among the following: Counterclockwise at 1 to oppose the field; zero at 2 because the field is uniform; clockwise at 3 to try to maintain the field. Clockwise at 1 to oppose the field; clockwise at 2 to maintain the field; clockwise at 3 to oppose the field. Clockwise at 1 to oppose the field; zero at 2 because the field is uniform; counterclockwise at 3 to try to maintain the field.

Explanation / Answer

lenzs law answers these it states the induced current in theloop
opposes the cause that induced it
hence in position 1 B created should be inward and hence currentclockwise direction
in 2 no current
in 3 current anticlockwise
hence the first option
