A handful of magnets are found on almost everyone's refrigerators at home. But how exactly do they work? To begin, the magnets on my fridge stick to it from both sides. When I attempt to make other metals stick to it, they simply fall. Therefore, the fridge must be magnetic attractable, meaning that it will be attracted to either side of a magnet and becomes polarized by the magnet. In addition, there are invisible magnet field lines on the magnet, flowing from north to south. The pictures of attached to the magnets between the magnet and the fridge only stay up due to the strength of the magnet. This explains why some of the magnets will not hold some of the heavier papers.
