magnetic poles attract each other.
However, while you can have a positive electric charge all by itself, you can’t have
a single magnetic pole all by itself: the existence of a lone magnetic pole has never
been confirmed. That is, there are no magnetic monopoles; magnetic poles always
exist in pairs. If you break a bar magnet into two pieces, it does not produce one
piece with just an N and another with just an S; it produces two separate, complete
magnets, each with an N-S pair.
