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.

Detailed explanation-2: -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-3: -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.

Detailed explanation-4: -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-5: -Explanation: When the like pole of two magnets comes close they repel each other because the direction of the line of force is opposite and when the opposite pole comes together they attract each other because the line of force points in the same direction.
