What is Pot Magnet?


    What is a pot magnet?

    The magnetic field line of a simple magnet distributes freely through the air. The permeability of steel shell much better than airs, so the magnetic field line pass easier in steel shell than in air. The magnetic field lines will focus on the working surface by the leading of the magnetic circuit. The magnetic field lines of the pot magnet are much more focused than a simple magnet after contact with the working surface, so its pull force also 32 times as strong as a simple magnet.

    Strong, compact and flexible. Those are the quality features of our pot magnets that allow you to use them at work or at home as well as in industry and craft, in schools and universities or for hobby and leisure. We can offer different styles, so you can select the magnet system that is right for your needs.

    The different parts of the pot magnet

    Magnet: Unlike the simple magnet, the pot magnet only exposes one face. For pot magnets, the magnetization direction of the magnet will via axial direction. The NdFeB, SmCo and ferrite are all suitable for pot magnets.

    Steel shell: The steel shell will help the magnet without crack and chip. Most magnets are brittle, the steel shell can ensure threaded hole and stub insert to assembly. The most important role of a steel shell is to rise the magnetic field.

    Spacer: The spacer can be made of plastic, epoxy resin and brass. The spacer situates between the magnet and steel shell to prevent the demagnetization of the magnet from the steel.

    Ningbo Tengxiao Magnetic Industry Co., Ltd. not only has pot magnets but also badge magnets and other products. Welcome customers at home and abroad to come to discuss cooperation.
