Q)

Read the passage below and answer the following question below <br><br> When the direction of relative motion between the magnet and the coil is reversed i.e; instead of bringing the magnet and the coil towards each other, if they are taken away from each other, the direction of deflection in the galvanometer (i.e; induced current in the coil) is also reversed. It is due to the reason that when we being the magnet and the coil closer to each other, the magnetic flux linked with the coil increases whereas when these are moved away from each other, the magnetic flux linked with the coil decreases. Thus it is the change (whether an increase or a decrease) in magnetic flux in the coil which induces current in the coil. Increasing magnetic flux induces current in one direction whereas decreasing magnetic flux induces current in the opposite direction. <br><br> Question : What is the factor which induces the current in the coil?

$\begin{array}{1 1} (a)\; \text{change in magnetic flux} \\ (b)\; \text{distance between the coil and the magnet} \\ (c)\; \text{total number of magnetic lines} \\ (d)\; \text{none of the above} \end{array}$
