Detailed explanation-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 the unlike poles of a bar magnet face each other the magnetic lines of force are in the same direction and hence unlike poles attract each other.

Detailed explanation-2: -Like poles of magnets always repel each other and unlike poles attract. Thus, the north and south poles of two magnets will attract each other.

Detailed explanation-3: -Like poles of the magnets i.e. north-north and south-south repel each other and unlike poles of the magnets i.e. north-south and south-north attract each other. This is a property of a magnet.

Detailed explanation-4: -Magnets with opposing poles attract one another. Bar magnets exhibit opposite pole attraction. When we bring the north pole of one magnet near the south pole of another, they attract each other.

Detailed explanation-5: -Like poles of magnets repel each other and unlike poles attract each other.
