A neodymium magnet is actually an alloy of neodymium, iron, and boron that forms a crystalline structure with formula Nd2Fe14B. Ferromagnetic materials like neodymium magnets are composed of microscopic regions called magnetic domains that align in the same direction when exposed to an external magnetic field. When practically all the domains are lined up, the material is at it’s saturation magnetization. At this saturation point, a neodymium magnet has a stronger magnetic field than other magnets.
