GEOLOGY

Detailed explanation-1: -The two ends of the bar magnet exert the maximum magnetic force. It is equally strong at the north pole and the south pole. The force exerted by the middle of the magnet is weaker.

Detailed explanation-2: -The Earth’s magnetic field is stronger near the poles of the planet, such as the North Pole and the South Pole. Looking at a regular magnetic bar, we can see that it has a stronger magnetic force near its north and south pole, or the ends of the bar.

Detailed explanation-3: -The magnetic field is strongest at the center and weakest between the two poles just outside the bar magnet. The magnetic field lines are densest at the center and least dense between the two poles just outside the bar magnet.

Detailed explanation-4: -The magnetic field is strongest at the poles as the field lines are very close to each other near the poles.

Detailed explanation-5: -The pulling or pushing force of a magnet is strongest at the edges of the magnet. These ‘edges’ are also called the poles of a magnet.
