MAGNETI IN NEODIMIO VS FERRITE: LA GUIDA COMPLETA
A neodymium magnet (also known as NdFeB, NIB or Neo magnet) is the most widely used type of rare-earth magnet. It is a permanent magnet made from an alloy of neodymium, iron, and boron to form the Nd2Fe14B tetragonal crystalline structure. Developed independently in 1984 by General Motors … See more General Motors (GM) and Sumitomo Special Metals independently discovered the Nd2Fe14B compound almost simultaneously in 1984. The research was initially driven by the high raw materials cost of See more In its pure form, neodymium has magnetic properties—specifically, it is antiferromagnetic—but only at low temperatures, below 19 K (−254.2 °C; −425.5 °F). But some compounds of neodymium with transition metals such as iron See more Sintered Nd2Fe14B tends to be vulnerable to corrosion, especially along grain boundaries of a sintered magnet. This type of corrosion can … See more The greater forces exerted by rare-earth magnets create hazards that may not occur with other types of magnet. Neodymium magnets larger than a few cubic centimeters are strong enough to cause injuries to body parts pinched between two … See more Grades Neodymium magnets are graded according to their maximum energy product, which relates to the magnetic flux output per unit volume. Higher values indicate stronger magnets. For sintered NdFeB magnets, there is a … See more Neodymium has a negative coefficient, meaning the coercivity along with the magnetic energy density (BHmax) decreases with … See more There are two principal neodymium magnet manufacturing methods: • Classical powder metallurgy or sintered magnet process See more WebNeodymium. double hexagonal close-packed (dhcp) Neodymium is a chemical element with the symbol Nd and atomic number 60.
