An iron nail near a bar magnet feels a net attraction because
Athe nail has a net charge
Bgravity pulls the nail down
Cthe field is uniform there
Dthe nail gains an induced moment
Answer & Solution
Correct answer: D. the nail gains an induced moment
The nail gets an induced moment, and its nearer induced pole feels a stronger pull in the non-uniform field.
