Neodymium Magnets Handling Guidelines Neodymium Magnets are very strong and powerful. Their magnetic power allows them able to generate some magic effect. They are interesting but are not toys. Their special physical properties determine that they are easy to be damaged in magnetic characteristics and need to be handled with extreme care and precision to [...]
How does a magnet work? Atomic structure Magnetic atom: protons with north and south poles, electrons with north and south poles, and neutrons The way a magnet works is determined by its overall atomic structure. Every atom is made up of negative electrons circling around positive protons and neutrons (called a nucleus), which are effectively [...]
Neodymium Magnet Manufacturing Methods, Sintered Neodymium Iron Boron Magnets, Bonded Neodymium Magnets Sintered Neodymium Iron Boron Magnets: The sintered Neodymium Iron Boron magnet is produced by the OPS (orient-press-sinter) method. A crystalline alloy of Neodymium, Iron, and Boron is ground to a sub-micron powder using a ball mill, then aligned in a strong magnetic field, [...]
Neodymium Iron Boron Magnet Material Overview Neodymium Iron Boron (NdFeB) magnets were commercially introduced in the early 1980s, and are widely used today for many different applications. The cost of neodymium magnet material (on a dollar per energy product basis) is comparable to that of ferrite magnets. * NdFeB magnets are covered by various patents [...]
NdFeB Magnets General Information Collectively known as Rare Earth magnets, Neodymium Iron Boron (NdFeB) and Samarium Cobalt (SmCo) magnets are alloys of the Lanthanide group of elements. Rare Earth magnets are the most advanced commercialized permanent magnet materials today. NdFeB magnets are available in a number of different grades that span a wide range of [...]
Neodymium Magnet Description The tetragonal Nd2Fe14B crystal structure has exceptionally high uniaxial magnetocrystalline anisotropy (HA~7 teslas - magnetic field strength H in A/m versus magnetic moment in A.m2). This gives the compound the potential to have high coercivity (i.e., resistance to being demagnetized). The compound also has a high saturation magnetization (Js ~1.6 T or [...]
