the impossibility of magnetic monopoles is a strong belief in standard physics: all magnets have two poles ("north" and "south") and if we break a magnet in two, we always form a new pair of dipoles.
And yet, this is apparently violated by all magnets on our fridge: they stick to the fridge on one side, but if you flip them on the other side, they just fall down, as if they only have one magnetic polarity.
Why is that?
