Detailed explanation-1: -The effect of magnetism is the strongest at the ends of a magnet. We call these two ends the poles. Hence the strength of a magnet is maximum at both of its poles.
Detailed explanation-2: -THE MAGNETIC FORCE IS CONCENTRATED AT THE TWO ENDS OR POLES OF A MAGNET. The magnetic field of a bar magnet is strongest at either pole of the magnet. It is equally strong at the north pole 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 magnetic field is strongest at the poles as the field lines are very close to each other near the poles.
Detailed explanation-4: -Since magnetic lines of force are crowded at north and south poles, magnetic strength is maximum at north and south poles.
