How do magnets attract themselves?

How do magnets, if rotated correctly, attract themselves?

Hi Alexandre!
Well, this is pretty complex, so let’s start with a simpler idea. When you stretch an elastic band, the work you do puts potential (stored) energy in the band. When you release the force, the elastic band snaps back, because things move in the direction which reduces the amount of potential energy. Pushing together like-poles (N-N or S-S) takes energy, so the magnets push each other apart (repel) to reduce the potential energy. When you put together two unlike poles (N-S), the potential energy in the magnetic field is reduced, pulling the magnets together (attraction).
