State four important properties of a bar magnet.

1.	State four important properties of a bar magnet.
Answer» 1. Attractive property: A magnet can attract small pieces of iron filing or other ferromagnetic materials. 2. Directive property: If a magnet is suspended horizontally by a thin thread (say silk thread), it rests always pointing north- south direction of earth. 3. Like poles always repel each other and unlike poles attract each other. 4. Poles always exist in pairs : Single pole can never exist.
