The basics of magnetism which we learn in school are simple.

Every physicist tells us the same principle, that the same magnets with opposite poles attract each other. This is clear and understand for most of us. But why in this case, the same magnets can attract when are facing each other with the same poles?

It's because there are three magnets there, not two: pins in the box are ferromagnetics, which can rearrange their magntic field to always "mirror" the external magnetic field and cancel it. So magnets are always attracted to that kind of metal, no matter their polarity. It they weren't, the fridge magnets couldn't work ;-)
