GEOLOGY

Detailed explanation-1: -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-2: -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-3: -Unlike-poles attract: When a north pole and south pole point together, the arrows point in the SAME direction so the field lines can join up and the magnets pull together (attract).

Detailed explanation-4: -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-5: -One simple rule to remember with magnets is that opposites attract. Every magnet has a north pole and a south pole. Placing two unlike poles together causes them to attract. When you try to place two like poles together (north to north or south to south), they will repel each other.
