Magnetic poles always exist in pairs. If you cut a bar magnet, you don't separate the north and south poles; instead, each resulting piece becomes a new magnet with its own north and south pole. Cutting parallel to the axis divides the magnet into two thinner magnets, each retaining its original length and thus forming new poles on the cut surface.
