Explanation:
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: -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-3: -It is strongest at the poles. So, what are magnetic poles? Magnetic poles are opposite ends of a magnet where the magnetic field is strongest.
