The south poles stick together with the right hand
rule but the north poles only resist sticking to
each other for straight bar magnets. The north and south
poles probably stick together but thats the weak force.
Try a "real" bar magnet to find out if that old north pole
resists sticking to standard steel. Einstein thought that
only the north and south poles stick together but Einstein
eats with a fork. I'm not sure how powerfull electro-magnets
can be if you wire them the right hand way, straight up.
