According to the materials of logos used as promotional magnets and souvenir fridge magnets, refrigerator magnets can be made from rubber, PVC, polyresin, metal, porcelain, epoxy or mixed some of these materials. Why do magnets stick to refrigerators? A property called a "magnetic moment" (or "magnetic dipole moment") characterizes the magnet's overall magnetic properties. The more magnetic moments are oriented, and the better their orientation, the more successful magnetization and the higher the net magnetic moment of the final magnet. The direction of the magnetic moment points from the magnet's south pole to its north pole, and the magnitude (strength) relates to how strong and how far apart these poles are.
