A light disc made of aluminium (a nonmagnetic material) is kept horizontally and is free to rotate about its axis as shown in the figure. A strong magnet is held vertically at a point above the disc away from its axis. On revolving the magnet about the axis of the disc, the disc will (figure is schematic and not drawn to scale)

A

rotate in the direction opposite to the direction of magnet’s motion

B

rotate in the same direction as the direction of magnet’s motion

C

not rotate and its temperature will remain unchanged

D

not rotate but its temperature will slowly rise
