GEOLOGY

Detailed explanation-1: -Like poles of a magnet repel each other. So, if the south pole of the magnet repels the end A of another magnet then the end A must be a south pole.

Detailed explanation-2: -If you hold two magnets the wrong way around, they push apart-they repel! In other words, if you hold two magnets together so that like-poles are close together (two norths OR two souths), they repel. Try it! It feels like the magnets are surrounded by an invisible rubber layer pushing them apart.

Detailed explanation-3: -The opposite poles of magnets will pull toward each other. The poles are said to attract each other.

Detailed explanation-4: -However, in Experiment 3, when you move the south pole of a magnet toward the south pole of another magnet, the two magnets repel each other and you cannot move them together. The rule for magnetic poles is that like poles repel each other and unlike poles attract each other.

Detailed explanation-5: -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.
