Detailed explanation-1: -When a bar magnet is cut into half both the halves will have a north pole and a south pole each. Magnets cannot have isolated poles. A new north pole and south pole will be formed at the edges where the bar magnet is cut as shown in the figure. So, the two halves will attract each other.

Detailed explanation-2: -Expert Answer. When a bar magnet is cut into half, two new magnets are generated and both parts will have North and South poles. So, cutting does not destroy its magnetic properties.

Detailed explanation-3: -Do you obtain one magnet with two south poles and one magnet with two north poles? The answer is no: Each half of the bar magnet has a north pole and a south pole. You can even continue cutting each piece of the bar magnet in half, and you will always obtain a new, smaller magnet with two opposite poles.

Detailed explanation-4: -When opposite poles of the magnets approach, they attract each other. Any north-south combination will pull them together. But when two like poles come together, they push each other apart. Two north poles will not stick together.

Detailed explanation-5: -Cutting a bar magnet into three equal parts will make three identical bar magnets. We know that each bar magnet has two poles. So, three bar magnet will have a total of 6 poles.
