Answer to Question #16448 in Electromagnetism for apoorv

Question #16448
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.
