Vedclass · Answer

(A) According to Faraday's law of electromagnetic induction,the induced emf in a coil is given by $e = -N \frac{d\phi}{dt}$.Here,$N$ represents the number of turns in the coil.As the number of turns $N$ increases,the magnitude of the induced emf increases.According to Lenz's law,the induced current creates a magnetic field that opposes the change in magnetic flux that produced it.When a magnet is moved into a coil,the induced emf in each loop creates a current that opposes the motion of the magnet.Since more loops result in a larger total induced emf,the opposing force becomes greater,making it more difficult to move the magnet.Therefore,both $A$ and $R$ are true,and $R$ is the correct explanation for $A$.

Assertion $(A)$: It is more difficult to move a magnet into a coil with more loops.
Reason $(R)$: This is because the emf induced in each current loop resists the motion of the magnet.
