The N28AH Neodymium Magnets strength of neodymium magnets is due to several factors. The tetragonal Nd2Fe14B crystal structure has exceptionally high uniaxial magnetocrystalline anisotropy (HA ~7 T – magnetic field strength H in units of A/m versus magnetic moment in A·m2). This means a crystal of the material preferentially magnetizes along a specific crystal axis, but is very difficult to magnetize in other directions. Like other magnets, the neodymium magnet alloy is composed of microcrystalline grains which are aligned in a powerful magnetic field during manufacture so their magnetic axes all point in the same direction. The resistance of the crystal lattice to turning its direction of magnetization gives the compound a very high coercivity, or resistance to being demagnetized.
Permanent Magnet REFeB Strong Disc Neodymium Magnets
At HSMAG PERMANENTMAGNETI we take pride in having manufactured some of the most complex magnetic assemblies produced anywhere.
Producing ultra-complex and sophisticated assemblies has given us know-how we’ve applied to other assemblies we build on a regular basis. The result faster, better and lower cost!
In addition, the greater strength of neodymium magnets has inspired new applications in areas where magnets were not used before, such as magnetic jewelry clasps, children’s magnetic building sets (and other neodymium magnet toys) and as part of the closing mechanism of modern sport parachute equipment. They also are the main metal in the formerly popular desk-toy magnets, “Buckyballs”, though some US retailers have chosen not to sell them due to child-safety concerns.
