Here's why:

* Magnetic Domains: A magnet's magnetism comes from the alignment of tiny magnetic domains within the material.

* Cutting the Magnet: When you cut the magnet, you are essentially separating these aligned domains.

* New Poles: Each new piece will have its own set of aligned domains, creating a new north and south pole on each piece.

So, instead of eliminating the magnetic poles, you actually create two new magnets with their own poles.
