When a piece of bar magnet is bisected parallel to its axis, two new bar magnets are formed.

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.

The pole strength of a bar magnet’s north pole is equal in magnitude to that of its south pole, although they are opposite in nature. Cutting a magnet perpendicular to its axis results in shorter magnets, each with a full set of poles. Magnetic monopoles (isolated north or south poles) have not been observed in nature.
