GEOLOGY

Detailed explanation-1: -Magnetic lines being close together mean a strong magnetic field and lines far apart from each other mean a weak magnetic field. The magnetic field is the strongest at the poles of a magnet, so the lines are closer to each other at poles.

Detailed explanation-2: -It is the magnetic force that attracts and repels. The force is stronger when magnetic objects are closer together. The force weakens when magnetic objects are farther apart. List some examples of how magnets are used in daily life.

Detailed explanation-3: -For a magnet, the flux lines repel each other so the field will be weaker at the sides. But they are concentrated at the poles, where they originate, so the field is stronger.

Detailed explanation-4: -The closer the lines are to each other, the stronger the magnetic field is at that point. As the field lines are drawn closer together at the two poles, this shows that the magnetic field and force of magnetism is strongest at the poles of the magnet.

Detailed explanation-5: -The magnetic field around a magnet is the strongest at the poles. The maximum number of magnetic field lines pass through the poles.
