A vertical bar magnet is dropped along the axis of a fixed metallic coil as shown in Fig. I. In Fig. II the magnet is fixed and the horizontal coil is dropped. If the accelerations are a₁ and a₂ respectively, then:

Question

G1 Physics · Accepted Answer

In both cases, Lenz’s law gives a magnetic force opposing the relative motion. Hence the falling body has acceleration less than g in each case: a₁<g and a₂<g. Therefore option C.
