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 magnetic field of a bar magnet is strongest at either pole of the magnet. It is equally strong at the north pole when compared with the south pole. The force is weaker in the middle of the magnet and halfway between the pole and the center.

Detailed explanation-3: -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-4: -Answer and Explanation: The magnetic field of a magnet is strongest at the poles. A magnet is a source of a magnetic field and has two poles. These poles are named the north and south poles, and are characterized by the direction of the magnetic field associated with them.

Detailed explanation-5: -The magnetic field is strongest at the poles as the field lines are very close to each other near the poles.
