Physics - EMI/AC Question with Solution | TestHub

As a given pole ($\mathrm{N}$or$\mathrm{S}$) of suspended magnet goes into the coil and comes out of it, current is induced in the coil in two opposite directions. Therefore, galvanometer deflection goes to left and right both. As the amplitude of oscillation of magnet goes on decreasing, so does the amplitude of  deflection.
