The correct answer is:
Attract \( N_{1} \) strongly,\( N_{2} \) weakly and repel \( N_{3} \) weakly
Given, \( N_{1} \) is ferromagnetic, \( N_{2} \) is paramagnetic; \( N_{3} \) is diamagnetic.
Therefore, \( N_{1} \) is attracted strongly by magnet. \( N_{2} \) is attracted weakly by magnet.
\( N_{2} \) is weakly repelled by magnet.
Therefore, \( N_{1} \) is attracted strongly by magnet. \( N_{2} \) is attracted weakly by magnet.
\( N_{2} \) is weakly repelled by magnet.
