| Magnet assemblies are constructed from more than one material. Usually this consists of one of the above magnet material and a metal coating or housing. This is to add protection to magnet materials and / or to allow a magnet to be constructed with a feature, such as a screw thread, which is not possible using the magnet material alone. Pot Magnets Most of our magnetic assemblies are pot magnets, where the metal housing is an essential part of the magnetic circuit. The two magnetic poles are concentric and are both on the end face of the magnet. Pot magnets are the most efficient design for gripping (other designs are preferable for lifting and attracting across air gaps). Features: - No stray flux as magnetism is retained in a closed circuit
- The pot screens the magnet material from de-magnetising effects
- Pot is machineable
- Can be inserted into or fitted to, steel without adverse effect (this cannot be done with unscreened magnets)
- The magnet itself is the most efficient magnet shape: plain cylinder magnetised lengthways
- Concentration of flux in the mild steel housing can be twice that of the magnet itself creating increased gripping power
- Distance of magnetic attraction lower than that of other magnets but grip in intimate contact is vastly superior to magnets of similar material and weight but different design.
