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.
Numbers and figures are an essential part of our world, necessary for almost everything we do every day. As important…
