Lenz’s Law and Coil Loops

Assertion (A): It is more difficult to push a magnet into a coil with more loops.
Reason (R): This is because emf induced in each current loop resists the motion of the magnet.
 
Both (A) & (R) are true and the (R) is the correct explanation of the (A)
Both (A) & (R) are true but the (R) is not the correct explanation of the (A)
(A) is true but (R) is false
Both (A) and (R) are false

Solution:

Assertion (A) is true. More loops increase induced emf and current, strengthening the opposing magnetic field. Reason (R) is true due to Lenz's law, where induced effects oppose the cause. (R) provides the direct explanation for (A).
