I have some permanent "refrigerator" magnets and noticed that, though they attract the refrigerator, they also attract each other (there is only one side available for the magnet, the other side has a plastic shell). This is odd because they "should" repel each other.
How is it, that the magnets can attract the refrigerator and also each other?
I have a couple ideas but none of them make complete sense. For example, the magnetic domain of the refrigerator (refrigerator is ferro-magnetic) is then directed towards the direction of the magnetic field of the permanent magnet hence the attraction. But what direction is the magnetic moment in the permanent magnet? Perhaps the answer lies in the direction of the magnetic moment of the permanent magnets.
Any insight is appreciated.
