Basically reversing the current will reverse the poles. So change the + and - inputs into the electromagnet and you will reverse the poles.
Either that way ot just turn it end over end...

extraordinary hand rule. Wrap your extraordinary hand arms around the coil interior the path of the present. Your thumb factors interior the path of B, the magnetic container. substitute the present path and you need to wrap your RH arms around the coil interior the choice path. once you do this, your thumb and the B container are pointing interior the choice path. N and S pole are meaningless words. One is the choice of the different...era. So in case you designate the B path out of the coil as N, then the different end, the place B is into the coil, must be S via definition. it relatively is plenty greater significant to easily say the B vector is out or into the coil at a given end.
