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: -Each pole is either north facing or south facing. If you break a magnet into two pieces each piece will still have a north pole and a south pole. No matter how small the piece of magnet is, it will always have a north pole and a south pole.
Detailed explanation-3: -If you cut a magnet in half, you get 2 new magnets with each, a north pole and a south pole, so on if you start again.
Detailed explanation-4: -Nope. If you cut one magnet into two pieces you get two similar magnets, each has a north pole and a south pole. What you are trying to produce is called a magnetic monople. They just don’t exist.
Detailed explanation-5: -No, we cannot isolate north pole or south pole from the magnet. This is because if we break a bar magnet into two halves, we will not get a single north or south pole but two different magnets each with its north and south poles.
