Final answer:

To identify the poles of an unlabeled bar magnet, use a compass and observe how the needle aligns.


Explanation:

To determine the north and south poles of an unlabeled bar magnet, you can use a compass. When a compass is brought close to the magnet, the needle of the compass will align in a specific manner, indicating the magnetic orientation of the bar magnet. The end that attracts the north-seeking pole of the compass is the north pole of the bar magnet.
