GEOLOGY

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: -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-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.

Detailed explanation-4: -Opposite poles of two different magnets repel each other.

Detailed explanation-5: -If you line up two magnets so that the south pole of one faces the north pole of the other, the magnets will pull toward each other. This is called attraction. 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.
