Magnetism of the magnet is lost when it is thrown down or heated

magnetEveryone knows about magnet but many of us don’t think what happens to magnet when it is heated. Magnetic substances have proper arrangement of atoms and this arrangement is effected when it is dropped from a height or when heated or beaten with a rod. Opposite forces are formed and it loses its magnetism. So the devices which work with magnetic fields should be thrown down or they should be heated or placed in sun.
