Strong permanent magnets made from alloys of rare earth elements.
Add Comment. Known for being one of the magnet rare earths and a key material in the strongest rare earth magnets currently available, neodymium is certainly an element that rare earths investors will want to be familiar with. Neodymium-iron-boron magnets are used in a range of modern technological applications. Below, Resource Investing News takes a look at what neodymium is, how it’s used and how supply risks for the metal are affecting the market. Neodymium magnets are a member of the Rare Earth magnet family and are the most powerful permanent magnets in the world. They are also referred to as NdFeB magnets, or NIB, because they are composed mainly of Neodymium (Nd), Iron (Fe) and Boron (B).  Internet # 204721291. Rare Earth magnets are the strongest type of permanent magnet currently made. They are amazingly powerful for their size and have innumerable uses. These disc magnets are 1/4 in. Diameter and 1/10 in. thick. They are magnetized through the thickness.  Rare-earth magnets are strong permanent magnets made from alloys of rare earth elements. Developed in the 1970s and '80s, rare-earth magnets are the strongest type of permanent magnets made, producing significantly stronger magnetic fields than other types such as ferrite or alnico magnets. The advantage of the rare earth compounds over other magnets is that their crystalline structures have very high magnetic anisotropy. This means that a crystal of the material is easy to magnetize in one particular direction, but resists being magnetized in any other direction. A rare earth element (REE) or rare earth metal (REM), as defined by IUPAC, is one of a set of seventeen chemical elements in the periodic table, specifically the fifteen lanthanides, as well as scandium and yttrium.  Neodymium magnets, invented in the 1980s, are the strongest and most affordable type of rare-earth magnet. They are made of an alloy of neodymium, iron and boron (Nd 2 Fe 14 B), sometimes abbreviated as NIB. The advantage of the rare earth compounds over other magnets is that their crystalline structures have very high magnetic anisotropy. This means that a crystal of the material is easy to magnetize in one particular direction, but resists being magnetized in any other direction. The magnetic field typically produced by rare-earth magnets can be in excess of 1.4 teslas, whereas ferrite or ceramic magnets typically exhibit fields of 0.5 to 1 tesla. There are two types: neodymium magnets and samarium-cobalt magnets. The advantage of the rare earth compounds over other magnets is that their crystalline structures have very high magnetic anisotropy. This means that a crystal of the material is easy to magnetize in one particular direction, but resists being magnetized in any other direction. To fully understand rare earth magnets, it is important to understand what they are made of and where they come from. There are 17 elements in the periodic table included in the rare earth family, the fifteen elements known as lanthanides plus scandium and yttrium. Rare earth magnets are used when space is at a premium or the greatest possible magnetic pull is required. While they are vital for many technology, manufacturing and engineering industries they are equally as popular for hobbies, crafts and DIY due to their performance and affordability. SmCo Magnet is also Rare Earth Magnet since the samarium is one of the rare earth elements. But in today's terminology, people use Rare Earth Manget to refer to the Neodymium Magnet and SmCo Magnet to refer to the Samarium Cobalt Magnet instead of calling them Rare Earth Magnet. Normally the Neodymium Magnets refer to Sintered Neodymium Iron Boron Magnets, or Sintered NdFeB Magnets in short. Since Neodymium element is one of the rare earth elements, so the Neodymium Magnets are also called Rare Earth Magnets.
