प्रश्न
Thamizh Dharaga and Sangamithirai were playing with a bar magnet. They put the magnet down and it broke into four pieces. How many poles will be there?

उत्तर
Each broken piece behaves like a separate magnet. Therefore, four pieces will have eight poles.
Conclusion:
Thus, we can conclude that unlike poles of a magnet attract each other, i.e., the north pole and the south pole of a magnet attract each other.
