GEOLOGY

Detailed explanation-1: -Bringing two north poles together-or two south poles-will cause a repulsion, and the magnetic field lines will bend away from each other.

Detailed explanation-2: -If two north poles or two south poles are brought near each other, the force will be repulsive. If a north pole is brought near a south pole, the force will be attractive.

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: -The density of the magnetic field lines is higher near the poles where the magnetic force is stronger. 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-5: -The like poles of magnets repel and unlike poles attarct each other. This is the reason why bringing the like poles of two magnets close makes them repel each other.
