Pot Magnet

Either pot magnet or cup magnets it is named after its shape and they both refer to the same group of magnetic products. By gluing a round shape magnet into a steel pot/cup you get a prototype pot magnet and based on that prototype there are so many extensions being made by adding different accessories, using different shape components. Some of them could look so different from the prototype pot magnet but as far as their core working principle does not change, we still call them "pot magnet". With the emerge of extension products, other names are also used such as round base magnet, hook magnet, NdFeB pot magnet, flat pot magnet, ferrite pot magnet, pot magnetic assembly from China, China countersunk pot magnet, etc.

Application of Pot Magnet

  • When you want to, for example, hold something, fix something, either permanently or temporarily and it could be a label, a poster, a piece of tool, a Christmas wreath, a note, etc.

  • More importantly, if you want to do it with ease, then you might want to choose from our wide selection of pot magnets. Pot magnets from Weizhong Magnetics Co., Ltd, the pot magnet manufacturer and pot magnet supplier, come in different sizes, forces, and are mounted with different accessories to meet the application request as much as possible.

How to Choose the Most Suitable Pot Magnet for Your Application

Basically, the first priority for consideration goes to holding force – the one matches the weight of the object you are about to hold. More importantly, out of safety concern, if you are about to hold a heavy object, you should choose the pot magnet like the ferrite pot magnet that offers a higher force than the weight of the object. An extra 10% higher, at least, in force of pot magnet is advised and, of course, the higher the safer as long as it is within the budget.

Technical Advantages of Pot Magnet

These simple-looking pot magnets are carefully designed following the physical practice of utilizing magnetic field strength, where, by conducting the magnetic field strength via the steel pot, an alternating-pole-pattern of; "S-N-S" or "N-S-N" is made on the holding surface of the pot magnet, and, as a result, it generates even higher holding force than using just magnet without steel pot.

What is pot magnet?

Pot magnet refers to a group of magnetic assemblies that uses a metal pot to realize magnetic circuit design so that magnetic energy is mostly concentrated on the edge of the metal pot to create strong holding force on this side.

With this principal design, pot magnets come in various sizes and basically bigger size means higher holding force.

Screw holes, countersunk holes, through holes, etc are made on pot magnets to make it easier for mounting jobs. Accessories such as thread bush and clips are added so that pot magnets can be used in even more working situations.

How is pot magnet made?

In our case, we do not produce raw magnets, instead, we purchase them from our supplier. In our workshop, we produce metal pots with holes, thread bushes, clips, etc., and then glue the magnet and metal pot together to get the pot magnet.

It is not that any random combination of a magnet and a metal pot makes a good performance pot magnet. These pot magnets are out of magnetic circuit design and countless experiments to get their final specifications.

We must guarantee that either the magnet or the metal pot meets all the specifications, with which our ISO9001 certified manufacturing system and quality system play a major role.

The adhesive we are using was chosen after many tests and comparisons and proved to be most effective in gluing magnets with metal.

We have 15 automatic assembly lines and 8 manual assembly lines to produce pot magnets. With the automatic assembly lines, all the assembly work is computer program controlled to ensure preciseness. With the manual assembly lines, we put in automatic units to cover those key steps to avoid possible man-made errors. We produce millions of pot magnets every year and by using automatic machines we keep stabilized outstanding quality level for all the pot magnets we produce.

Tips for choosing pot magnets

There are many ways to categorize pot magnets and users can first choose the category and then the specific product that fits their application scenario.

For potential users that have zero experience with pot magnet, if they knew a little more about the magnets used in these products it would be easier for them to make decisions in a shorter time even if it is the first time they use pot magnet:

Among all our pot magnets we mainly use Neodymium magnet and Ferrite magnet , where Ferrite is a much weaker magnetic material than Neodymium (NdFeB) , but it is much cheaper than NdFeB.

So, to get the same holding force, pot magnet using Ferrite has a larger diameter than that using NdFeB. You can choose according to how the pot magnet is to work with other components if any, whether a big magnet fits better or a small one.

For two pieces of pot magnets of the same size, the NdFeB version is much more expensive and produces even stronger force. The Ferrite version is a good choice when a user has a low budget. NdFeB pot magnet goes to working condition that requires high safety margin.

FAQs about Pot Magnet

  • What is the strongest magnet?

    The strongest permanent magnets in the world are neodymium (Nd) magnets, they are magnetic material made from an alloy of neodymium, iron and boron to form the Nd2Fe14B structure.

  • What is a cup magnet?

    Cup magnets are magnets inset into steel cups that assist in mounting and increase their holding force. They are commonly used in holding applications where they are attached to a surface with a countersunk screw.

  • What is a pot magnet?

    A pot magnet is a permanent magnet encased in a steel shell, which is sometimes called a pot, hence the name 'pot' magnet. A permanent magnet emits a magnetic field without the need for any electricity. Pot magnets are often used as magnetic bases and magnetic holders for large supermarket ceiling signs.

  • How does a pot magnet work?

    A pot magnet works by attaching itself to ferromagnetic materials with the help of its magnetic field, or to non-ferromagnetic materials with the help of fittings (such as studs and threaded holes) on the top of its steel shell. ... The larger the pull force of the pot magnet, the more material it can attract.
