Vedclass · Answer

(C) According to Lenz's Law,the induced current in the coil always opposes the cause that produces it.In Fig-$I$,as the magnet falls towards the fixed coil,the magnetic flux through the coil increases. The coil develops an induced current that creates a magnetic pole (North pole) on its upper face to repel the falling magnet. This repulsive force acts upwards,opposing the gravitational force. Thus,the net acceleration of the magnet is $a_1 In Fig-$II$,as the coil falls towards the fixed magnet,the magnetic flux through the coil changes. The coil develops an induced current that creates a magnetic pole (North pole) on its lower face to repel the magnet below it. This repulsive force acts upwards on the falling coil,opposing its weight. Thus,the net acceleration of the coil is $a_2 Therefore,both $a_1 < g$ and $a_2 < g$.

$A$ vertical bar magnet is dropped from the shown position on the axis of a fixed metallic coil as shown in Fig-$I$. In Fig-$II$,the magnet is fixed and a horizontal coil is dropped. If the acceleration of the magnet and coil are $a_1$ and $a_2$ respectively,then:
