Why The N Pole And S Pole Of The Magnet Cannot Be Separated?

Magnets will attract each other, are mutually exclusive. This is because different names between the poles of attraction "gravity", between the poles of the same name there is mutually exclusive of "repulsion".

Prepare a bar magnet, use red to represent n, blue for the s pole, if two bar magnets, it is easy to assume that n and s poles apart, but it's not the truth. Because form magnet each atom has n and s pole. Magnet already exist in the atom n pole and s, so even if you split again and the small magnets, MagNet's poles will not separate. For a long time, scientists have been looking for a magnet with only one pole, the "magnetic monopoles". However, so far there is no find a magnet with only one pole.
