What are the basic properties associated with a magnet?
The basic properties associated with a magnet are:
1. Attractive Property - Magnet attracts ferromagnetic materials like iron, cobalt, and nickel. This property proves that the magnetic strength at the ends of the poles is strong.
2. Law of magnetic poles - Like poles repel each other, while unlike poles attract each other.
3. Directive Property - A freely suspended magnet in mid-air always points in a north-south direction. This property help us to understand which pole of the magnet is north and south.
4. Pair property - When a magnet is cut into two pieces, both the pieces will have the North Pole and the South Pole.
