## What are the Properties of a magnet?

• Consider a bar magnet. It has two poles: north and south.
• On suspending a bar magnet freely in space, it aligns itself in the north-south direction.

Bar magnet

• When the north pole of another bar magnet is brought near the north pole of the first one, both the magnets move away from each other. That is, they repel each other. If the south pole of the new magnet is brought near the north pole of the first one, then both the magnets move towards each other. That is, they attract each other. Thus, like poles repel and unlike ones attract.
