It is impossible to separate two opposite magnetic poles once they are in contact with each other.

Detailed explanation-1: -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-2: -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-3: -You can think of a magnet as a bundle of tiny magnets, called magnetic domains, that are jammed together. Each one reinforces the magnetic fields of the others. Each one has a tiny north and south pole. If you cut one in half, the newly cut faces will become the new north or south poles of the smaller pieces.
Detailed explanation-4: -This is a false statement because as the magnet is broken into two parts, the realignment of the magnetic lines takes place, and both parts will have their separate north and south poles.
Detailed explanation-5: -It can be natural to think that cutting a bar magnet in half will separate the north and south poles, but this is not what happens. Instead, it creates two smaller dipole magnets.
