Alnico Deep Pot Magnet
 Alnico pot magnet is a deep cylindrical permanent magnet which are assembled in a mild steel pot using spacers like Aluminum or Copper. The working temperature of this magnet is around 250° C. Outer surface except pole can be either painted or coated with Zinc, Nickel or Chrome. Assembly of the magnet and correct spacing are achieved by the use force-fitted aluminium ring . While working above 200°C, precaution must be taken of possible mechanical loosening through expansion and contraction of the component parts.
