Question

what happens if a bar magnet is divided into two parts​

Answer 1

when a bar magnet is broken into two parts then each piece Will have unlike poles.since magnetic monopole does not exist so if you do the breaking process repetitively then you will end up with each piece have unlike poles.

Answer 2

Answer:

You can think of a magnet as a bundle of tiny magnets, called magnetic domains, that are jammed together. Each one reinforces the magnetic fields of the others. Each one has a tiny north and south pole. If you cut one in half, the newly cut faces will become the new north or south poles of the smaller pieces.
