Question
A metal ring is dropped into a localized region of constantmagnetic field, as indicated in the figure . The magnetic field iszero above and below the region where it is finite. For each of the three indicated locations (1, 2, and 3), isthe induced current clockwise, counterclockwise, or zero? Choose the best explanation fromamong the following: Clockwise at 1 to oppose the field; zero at 2because the field is uniform; counterclockwise at 3 to try tomaintain the field.Counterclockwise at 1 to oppose the field; zeroat 2 because the field is uniform; clockwise at 3 to try tomaintain the field.

Explanation / Answer
in position 1 the ring has current and clockwise ( The fluxmagnetic increases) In posittion2 no current ( because the flux magnetic does notchange) In posittion 3 the ring has current and counterclockwise ( The fluxmagnetic decreases)
