Vedclass · Answer

(D) As the magnet oscillates in and out of the coil,the magnetic flux linked with the coil changes continuously.According to Faraday's law of electromagnetic induction,this change in flux induces an $e.m.f.$ in the coil,which causes a current to flow through the galvanometer $G$.When the magnet moves into the coil,the flux increases,and when it moves out,the flux decreases. This change in the direction of flux change causes the induced current to reverse its direction,resulting in deflection to both the left and right sides of the galvanometer.Due to the damping effect (air resistance and induced eddy currents in the coil),the amplitude of the magnet's oscillation decreases over time.Consequently,the magnitude of the induced $e.m.f.$ and the resulting deflection in the galvanometer also decrease steadily.

$A$ magnet $NS$ is suspended from a spring and while it oscillates,the magnet moves in and out of the coil $C$. The coil is connected to a galvanometer $G$. Then as the magnet oscillates,
