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: -Opposite poles of two different magnets repel each other.

Detailed explanation-3: -If you line the magnets up so that two of the same poles face each other, the magnets will push away. This is called repulsion. Opposite poles attract each other, but similar poles repel.

Detailed explanation-4: -A magnet has two poles-North and South pole. Similar poles of a magnet repel each other whereas opposite poles attract each other.

Detailed explanation-5: -Like poles of a magnet repel each other while opposite poles attract.
