Radial magnet hard ferrite ring

             New application of the radial multipole magnetic hard ferrite ring 

  A new application of the radial multipole magnetic hard ferrite ring: the ring whose magnetic flux densit is 

  sine wave shape on the surface, is made by new technology. Its magnetic property can reach about 210mT. Using

  this kind of multipolar magnetic rings to replace the traditional magnetic shoe can improve the dimensional 

  precision and reduce costs. The multipole magnetic rings are used to replace some bonded NdFeB multipole magnetic

 rings and its cost is only 1/3-1/4 of the magnetic shoe. It is acid-resitant and alkali-resitant and it can work in the severe environment.
