Hard Ferrite Magnetic Pot
The permanent pot magnets (magnet pot or magnetic pot) position ferromagnetic items quickly and easily in the required place. These magnet systems have only one surface of magnetic attraction. In other words, all the other sides are non-magnetic. This form of construction restricts the further spread of the magnetic field. As a result, other items or machine parts in the vicinity of the pot magnet do not become magnetised.
Pot magnets retain their magnet force indefinitely. Only increase in temperature and external magnetic fields can reduce their magnetic force.
