Pot Magnet is a very common product in magnetic components, and it can be seen in various production and life scenarios. There is a layer of steel shell on the outside of the pot magnet, which is shaped like a pot, hence its name. The combination of the magnet and the steel shell can optimize the magnetic circuit, enhance the unilateral magnetic force, and avoid the magnet from being bumped in use.
The structure and principle of pot magnet
The pot magnet is composed of three parts: magnet, steel shell and gasket:
Magnet: NdFeB, Samarium Cobalt, Ferrite, AlNiCo and other materials can be used to make pot magnets
Steel shell: general steel shell, the production process has two kinds of turning and stamping. The price of the stamping process is lower, and the dimensional accuracy of the turning process is higher, which can produce products with more size requirements, especially the larger diameter pot magnet products. (For the same size, the turning precision is higher)
Gasket: generally made of plastic, but also epoxy resin and brass.
Under normal circumstances, the magnetic field lines of the magnet are freely distributed in the air, and the pot magnet adds a steel shell outside the magnet, and the magnetic circuit guides the magnetic field lines to focus on the working surface. After the pot is magnetically attracted to the iron plate and touches the working surface, the magnetic lines of force gather much more than usual, so its pulling force is much larger than that of ordinary magnets.
Application of pot magnet
Pan magnets are often used in magnetic hooks, door stops, traction lights and magnetic clamps.
Types of pot magnets
The scope of application of the pot magnet is very wide, and it can be customized according to the needs of different usage scenarios. Generally speaking, it can be used for drilling or threading.
