Ferrite pot magnets are powerful magnetic assemblies which are available in various dimensions and diameters. These magnets have wide applications and are applicable at temperatures of up to 200°C. These pot magnets are encased in a non-magnetic cup and are ideal for holding and fixing applications.

Features
    ● Ferrite magnets have structural advantages as they have limited interior dimensions.
    ● They can be housed in a steel pot due to which the magnetic field can be screened off.
    ● The Ferrite magnets can be easily fastened that is they can be pressed, glued or screwed.
    ● Heating of Ferrite magnets decrease the magnetic force by 30% to 40%. However the magnetic force is restored to the normal ambient temperatures.

NdFeB pot magnets are made up of alloys of neodymium, iron and boron. These magnets have high magnetic strength as compared to ceramic pot magnets. The magnetic shield to these magnets are provided by the soft iron case. The protective covering over the magnets provide them with strong resistance against corrosion. The NdFeB magnets are workable under high temperature.

The NdFeB magnets should not be pressed directly into iron as it may cause short circuit and hence reduce the adhesive power of the magnets. NdFeB pot magnets can be recognized by the blue color on the magnetic side. Just like other pot magnets they too posses fastening qualities, that is they too can be pressed, screwed and glued.

Alnico pot magnets are strong permanent magnets with great temperature resistance and are applicable up to a temperature of 450^oc. Normally they are housed in a steel pot having non-magnetized materials like brass or aluminium in between. The magnetic force get reduced at high temperature however it is restored as the pot magnets get cooled in room temperature. The alnico pot magnets are available in different sizes and shapes. These magnets are primarily for gripping applications. The outer surface of the magnets can be either painted or coated with Zinc, Nickel or Chrome.

Types
Based on the designs and applications alnico pot magnets are ctegorized into following types:
Alnico Deep Pot Magnet
Alnico Shallow Pot Magnet
Alnico Magnetic Holdfast
Alnico Magnetic Foot
Alnico Deep Pot Magnet

Samarium cobalt pot magnets are powerful permanent magnets which are encased in a steel pot and are workable under very high temperatures that is 200° C. The magnetic force of these magnets are very high as compared to ceramic magnets due to which they have good resistance against demagnetization. Samarium pot magnets can be fastened that is they can be pressed, glued and screwed.

Despite they have a steel pot but this also does not provide any protection against flowing of magnetic force out. Thus while making pot magnet the distance between the steel element and the magnet should be maintained.

Applications
The samarium pot magnets have following applications:
    ● Welding moulds of spot-welding machines
    ● In very small tools
    ● In various gripping operations

Pot magnets are strong magnets that are developed for the current industrial needs. They are made up of magnets like NdFeB, SmCo, AlNiCo, hard ferrite, plastic, rubber and other components. These magnets can produce a magnetic field on its exclusive surface.
Pot magnets retain their magnet force indefinitely. Only increase in temperature and external magnetic fields can reduce their magnetic force.

Features
    ● These magnets have only one surface of magnetic attraction. This type of construction prevents further spread of magnetic field. Due to this, other items or machine parts in the vicinity of the pot magnets do not become magnetized.
    ● These magnets have ability to retain their magnetic force indefinitely.
    ● The magnetic force of these magnets are only affected by the increased temperature and external magnetic force.

Precautions
     ● The permanent pot magnets must not be exposed to radioactive radiations for longer duration as it might effect their magnetic strength.
     ● This can work within permissible temperature. If these magnets are used beyond permissible temperature limit it might again affect their magnetic strength.
