Currently, common materials on the market include ferrite, neodymium iron boron, samarium cobalt, and composite injection molded magnetic rings (injection molded ferrite/injection molded neodymium iron boron), among which ferrite magnetic rings are the most widely used.... ...More>>
Radial magnetization permanent magnet is mainly because its magnetization method is radial, and the maximum magnetic force surface is on the side. The reason why radial magnetization is used is to meet the needs of different customers. The following is an introduction to the shape and function of radial magnetization permanent magnets.... ...More>>

Different from the coercive force, when the reverse magnetic field H = Bc, although the magnetic induction intensity B of the magnet is 0, the magnet does not show magnetic flux to the outside, but the vector sum of the microscopic magnetic dipole moments inside the magnet is often not 0, and also That is to say, at this time, the magnetic polarization of the magnet tends to maintain a large value in the original direction.... ...More>>
According to common industry standards, the intrinsic coercivity of H-grade is ≥ 17 kOe (approximately 1353 kA/m), SH grade is ≥ 20 kOe (approximately 1592 kA/m), and UH grade is ≥ 25 kOe (approximately 1989 kA/m). Therefore, the intrinsic coercivity of the three is ranked as UH>SH>H... ...More>>
