The manufacturer of strong neodymium magnets tells you the mystery of strong neodymium magnets
The main component of strong neodymium magnets is the rare earth element neodymium. Rare earth is not called rare earth because of its low concentration, but it is more difficult to separate than other materials connected by chemical bonds.
The main component of strong neodymium magnets is the rare earth element neodymium. Rare earth is not called rare earth because of its low concentration, but it is more difficult to separate than other materials connected by chemical bonds. Although the magnetic attraction of strong neodymium magnets is very strong, it is even said that strong neodymium magnets can absorb 600 times their own weight. But in fact, this statement is not comprehensive, because the magnetic attraction is also affected by multiple conditions such as shape and distance. For example, for a magnet with the same diameter, the higher the magnet, the stronger the magnetic attraction; for the magnet with the same height, the larger the diameter, the greater the magnetic attraction.
The shiny magnets with anti-corrosion treatment on the surface are strong neodymium magnets, and its chemical formula is Nd2Fe14B. The most commonly used strong neodymium magnets are made by high-temperature sintering of neodymium, iron, and boron. They are by far the strongest artificial magnets. If iron is the core element of traditional Fe3O4, the reason why strong neodymium magnets have such strong magnetism is the effect of neodymium.
Neodymium is the fourth element in the lanthanide family of rare earth elements. Like iron, cobalt, nickel and the aforementioned gadolinium, it can also be attracted by magnets. In addition, neodymium is the more active of the lanthanide elements, so it is as easily oxidized as iron, which is why the surface of strong neodymium magnets is coated. If neodymium is used to enhance magnetism, then the role of boron should not be underestimated.
In the periodic table, boron is located to the left of carbon, so boron chemistry similar to carbon-centric organic chemistry has recently appeared. In strong neodymium magnets, boron is equivalent to the mediator of neodymium and iron. Boron greatly expands the maximum magnetism that a substance can produce while ensuring the stability of its molecular structure, making the entire strong neodymium magnets extremely high in magnetic properties, even allowing it to absorb objects 640 times its own weight.
