Detailed explanation-1: -When a bar magnet is cut into four pieces, it turned into four bar magnets and, every bar magnet has its own North and South pole.
Detailed explanation-2: -Hint:When a magnet is broken into pieces, each piece will behave as an individual magnet. Therefore, every broken piece will have a north pole and a south pole.
Detailed explanation-3: -So we can conclude that if a magnet is cut into four parts such that the length and width of each part are half that of the initial one, then the pole strength of each part will become half.
Detailed explanation-4: -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-5: -When a bar magnet is cut into 3 parts, each part has its own north and south pole. So the total number of poles is 6.
