About Neodymium Magnet    
    

Neodymium magnet is a sort of alloy called Nd2Fe14B or NdFeB that formed by Nd,Fe,B,and some transform
material like Dy, Ga and Pr. In order to meet different industrialor domestic needs,various of magnet formulas
and manufacturing methods have beediscovered and applied in the past 30 years.The super magnetism of Sintered NdFeB ( N52 is up to 52MGOE ) and moderate price half of SmCo magnets ) hence NdFeB magnet
has became the best 
commercial magnet and widely been applied in civil,  industrial,  tele-communication and medical areas. Due to the particularity of manufacturing technique,bonded isotropic NdFeB can easily mound into different shapes,  the BH max is up to 10 MGOE, only 20% of sintered type. Magnetism of NdFeB magnet
is 40 %-70 % higher than SmCo magnets,while price 
is half cheaper,When working temperature is over 220 ºC
SmCo is better than NdFeB on magnetic stablity and temperature coefficiency.The NdFeB magnets are usually axial direction magnetized or dia direction magnetized in magnetizing envioronment from 1 mgoe -100 mgoe it

The appliections of Neodymium Magnet

Ring Shaped Neodymium Magnet with Axial Holes

 Ring Shaped Neodymium Magnet with Axial Holes
 NdFeB Magnets own strong magnetism, which will higher the energy use ratio and saving more energy.Thus 
compared with electrical magnets. Neodymium magnets are commonly used on motor industrial areas.
Neodymium magnets are also can be applied in electricity generating,wind power, water power,thermal power. etc Neodymium Magnets are sensitive with magnets  and ferromagnetic matrials, thus the neodymiummagnet
are also can apply as  meters or sensors,  or operators. Neodymium magnet own strong manetic power, So it
also can be used as lifter or magnetic holding device.The famaous Halbach arrayis made up by cubic ndfeb magnets for the application on subway metro, Neodymium magnets also applied in medical area as MRI and
CT instruments. NdFeB magnets also  applied in food,oil,medical manufacturing purify the iron contaminant.
