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: -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.

Detailed explanation-3: -When opposite poles of the magnets approach, they attract each other. 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-4: -When will magnets attract or repel each other? The rule to remember is that opposites attract. 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.

Detailed explanation-5: -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.
