# Interactions Between the poles of the same magnet

Suppose a bar magnet like so :

[(+m)----------------(-m)]


Do the two individual poles interact with each other ?

If yes then how do you explain it if no then how?

There aren't two distinct poles. The battery is made up of lots of tiny magnets (e.g. iron atoms), and all those tiny magnets do indeed interact with other. The overall field of the magnet is the result of these interactions. The poles are just where the field leaves the end of the magnet.

So they interact or not? –  The-Ever-Kid Jul 26 '12 at 18:07
