Pot Magnet is a very common product in magnetic components and can be found in a variety of production and life scenarios.

Pot magnet has an outer steel shell shaped like a pot, hence the name pot magnet.
The combination of the magnet and the steel shell can optimize the magnetic circuit, enhance the unilateral magnetic force, and avoid the collision of the magnet in use.

1. The application of pot magnetic
Pot magnets are commonly used in magnetic hooks, door stops, traction lamps and magnetic fixtures.

2. Structure and principle of pot magnet
Pot magnet is composed of three parts: magnet, steel shell and gasket:
Magnets: Ndfeb, samarium cobalt, ferrite, aluminum nickel cobalt and other materials can make pot magnets
Steel shell: general steel shell, the production process has two turning and stamping.
The price of stamping process is lower, turning process dimensional accuracy is higher, can produce more size requirements of the product, especially the larger diameter of the pot magnetic products.
(For the same size, turning processing accuracy is higher)
Gasket: usually made of plastic, but also epoxy resin and brass.

While a magnet's lines of force are normally distributed freely in the air, pot magnets add a steel shell to the outside of the magnet, guided by magnetic paths that focus the lines on the working surface.

When the pot magnet is drawn to the iron plate and makes contact with the working surface, the magnetic field lines are much more concentrated than usual, so the tension is much greater than that of ordinary magnets.

3. Types of pot magnets
Pot magnetic applications are very wide, according to the needs of different use scenarios can be customized, in general can do drilling or threading.
