Detailed explanation-1: -Every magnet has both a north and a south pole. When you place the north pole of one magnet near the south pole of another magnet, they are attracted to one another. When you place like poles of two magnets near each other (north to north or south to south), they will repel each other.

Detailed explanation-2: -The south-seeking pole, or any pole similar to it, is called a south magnetic pole. Unlike poles of different magnets attract each other; like poles repel each other. The magnetic force between a pole of one long bar magnet and that of another was described by an inverse square law as early as 1750.

Detailed explanation-3: -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 poles facing each other, the lines of force are in opposite directions and hence like poles repel each other.

Detailed explanation-4: -A magnet has two ends called poles; one end is the north pole and the other is the south pole. A north pole will attract a south pole; the magnets pull on each other. But the two north poles will push each other away. We say the magnets repel each other.
