To find the poles, bring the marked magnet close to the unmarked one. The north pole of the marked magnet will attract the south pole and repel the north pole of the unmarked magnet, revealing its poles.
You are given a magnet which does not have the poles marked. How can you find its poles with the help of another magnet which has its poles marked?

To determine the poles of the unmarked magnet, bring the marked magnet’s north pole near each end of the unmarked magnet. The end that attracts the marked magnet’s north pole is the south pole, and the end that repels it is the north pole. This is because like poles repel, and unlike poles attract. Repeat the process with the marked magnet’s south pole to confirm the findings and accurately identify the poles of the unmarked magnet.
