About Block NdFeB Magnet
Neodymium magnets are manufactured on the basis of Nd-Fe-B alloys and sintered Neodymium magnets have the highest (BH)max value among all of commercially available permanent magnets. Neodymium ring magnets are circular in shape with a concentric hole inside it. Magnet ring can be divided to pure ring or countersunk ring based on the detailed shape of the inner hole. Neodymium ring magnet should be measured by outer diameter (O.D.), inner diameter (I.D.), and thickness (T). Similar to Neodymium disc magnet, ring shaped magnet can be magnetized with its N pole and S pole opposite flat end surfaces or diametrically magnetized so as to the N pole is on one curved side and the S pole is on opposite curved side. Besides the conventional axially magnetized or diametrically magnetized magnets, radially oriented ring magnet is also available in SDM. In addition, Neodymium magnets are easily corrode under humid condition and are necessary to cover with a protective coating.
