1. What happens when like magnetic poles are brought close together?​

They repel from each other

Explanation:

It is also observed that, magnets attract as well as repel. We can explain this dual nature of magnetic force by proposing that each magnet has two poles, north pole (N) and south pole (S). You will observe two things during the activities:

1) When two magnets are brought near each other, like poles repel; opposite poles attract.

2) When a magnet is brought near a piece of iron, the iron also gets attracted to the magnet, and it acquires the same ability to attract other pieces of iron.
