Question

Why do like poles of a magnet repel each other and unlike poles attract?

Answer 1

when two magnets are placed with their like poles facing each other the lines of force are in opposite directions and hence like poles repel each other
when unlike poles of a bar magnet face each other when the magnetic lines of force are in the same direction and hence unlike ploes attract each other

Answer 2

when a magnet is placed when it's like poles face each other, the lines of force are on opposite direction and hence like poles repel each other. When unlike poles of a bar magnet face each other, the magnetic lines of the force are in the same direction and hence unlike poles attract each other.
