A compass aligns with the magnetic field lines of the earth. Those lines run from North to south. So a compass will always point out where north is and where south is. In this way, a magnetic compass shows direction where to go. Therefore, a .....

Copper is diamagnetic, it has no unpaired electrons and will interact with magnetic fields only very weakly. Most "non-magnetic" materials (such as water, plastic, wood, etc.) are diamagnetic. Diamagnetic atoms have no unpaired outer .....

So, even if the magnet is broken, the magnetic moments are still aligned in the same direction, and each of the pieces has their own respective North and South poles. Hence, poles of a magnet cannot be .....
