1 If the distance between two magnets is doubled the magnetic force between them will fall to a quarter of the initial value. #(F//4)#.  If the distance between two magnets is halved the magnetic force between them will increase to four times the initial value. #(4F)#.
Magnets stay magnetized until something destabilizes them. The constant jostling of molecules (i.e. heat) slowly disorganizes the magnetic domains in a magnet, and this happens faster the hotter the magnet. Ultimately, a magnet will align itself to any pre-existing magnetic field, such as that of the Earth.I don't know how long it would take for a magnet on your refrigerator to demagnetize-probably longer than a human lifetime.agnets stay magnetized until something destabilizes them.
