NEET Physics Question - Electromagnetic Induction

A vertical bar magnet is dropped from position on the axis of a fixed metallic coil as shown in fig - I. In fig. II the magnet is fixed and horizontal coil is dropped. The acceleration of the magnet and coil are a1 and a2 respectively then Image related to

a1 > g , a2 > g

a1 > g , a2 < g

a1 < g , a2 < g

a1 < g , a2 > g

Solution:

In both cases, relative motion between the magnet and the coil induces a current that creates a magnetic force opposing the motion (Lenz's Law). This upward retarding force reduces the downward acceleration below gravity ( $g$ ), resulting in $a_1 < g$ and $a_2 < g$ .
