Detailed explanation-1: -Any north-south combination will pull them together. But when two like poles come together, they push each other apart. Two north poles will not stick together.
Detailed explanation-2: -In magnets like poles repel each other and unlike poles attract each other. So when placing the north pole of two magnets close together they will repel.
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: -The density of the magnetic field lines is higher near the poles where the magnetic force is stronger. When two magnets are placed with their like(same) poles facing each other, the lines of force are in opposite directions and hence like(same) poles repel each other.
