JEE AdvancedPhysicsMagnetismMCQ+3 / −1
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) JEE Advanced 2020 Paper 1 Offline Physics - Magnetism Question 39 English
