Ferrite pot magnets
Pot magnets consists of magnet material enclosed in a metal pot. The active magnet face is kept open.
The pot 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, lifting and attracting across air gaps
No loss of magnetism as the magnet is retained in a closed circuit
The pot screens the magnet material from de-magnetising effects
Pot is machineable
Can be inserted into, fitted to, steel without adverse effect
Magnet proper is most efficient magnet shape
