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.
