Why does it seem like a broken magnet's poles flip?
I have experienced that if we break a bar magnet into two pieces and try to bring those broken faces together it gets repelled each other. Why is it so?
consider a bar magnet,
$ NN--------SS $
$NN$ for north pole and $SS$ for south pole.
I broke that into two pieces, So one piece would be
$ NN--SS'$ and another piece would be $'NN--SS$ .( $'$ indicates the broken part).
Now if I bring those two together, $SS'$ of first should attract the $'NN$ of the other. But in the reality it is getting repelled.
or is there any pole exchange occuring? $$NN--------SS$$
gives either $$NN---SS'$$ and $$'SS---NN$$ OR $$SS---NN'$$ and $$NN'---SS$$
so it will repel each other.
Please explain why is this happening?
Edit: The cut has been made perpendicular to the polar axis.
