Assertion: When a magnet is brought near iron nails, only translatory force act on it. Reason: The field due to a magnet is generally uniform. (A) If both assertion and reason are true and reason is the correct explanation of assertion (B) If both assertion and reason are true but reason is not the correct explanation of assertion (C) If assertion is true but reason is false (D) If both assertion and reason are false

The field due to a magnet is non-uniform. Therefore, it exerts both a net force and a torque on the nails which will translate arid also rotate the nails before striking to north pole of magnet with their induced south pole and vice-versa. Hence, option (d) is correct.
