There are no individual magnetic poles (or magnetic charges). Electric charges can
be separated, but magnetic poles always come in pairs
- one north and one south.

Opposite poles (N and S) attract and like poles (N and N, or S and S) repel.

These bar magnets will remain "permanent" until something
happens to eliminate the alignment of atomic magnets
in the bar.
