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. Depending on the usage, pot magnets are of different size, shape and width. Different types of pot magnets functions in different temperature. However they
give same result in the normal temperature.
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.
These magnets are versatile magnets which are designed for various industrial applications. The popular industries in which these magnets are used are as follows:
The metal and steel industry
Used to position ferrous-magnetic work pieces
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.
