What is pot magnet? Pot magnet Guide

     As you can see, the pot magnet is a combination of powerful sintered Ndfeb magnets embedded in a steel housing or slot. Because it looks like a pot or cup, it is called a pot magnet. The permanent magnet is easy to be broken, so the steel shell outside the pan magnet forms a safe protective layer, and also provides a magnetic shielding layer, which solves the problem of the limited magnetic force of the permanent magnet and concentrates the magnetic force on a surface. Most pot magnets can be heated to 80 degrees Celsius without losing their magnetism.

     Types of pot magnets and extensions

1. Depending on the shape

     Pot magnet can be divided into round pot magnet and rectangular pot magnet. Round pot magnet can be further divided into round pot magnet with countersunk hole, round straight hole pot magnet, round pot magnet with screwed bush, round pot magnet with internal thread, round flat thread pot magnet and so on; Rectangular pot magnet can be subdivided into rectangular neodymium pot magnet with counter bore and rectangular pot magnet with two countersunk holes.

2. Extension of pot magnet

     Different kinds of magnetic hooks, such as neodymium magnet with eyelet hook, neodymium magnetic swivel hook, their bases are round pot magnets; Similarly, both single-sided and double-sided fishing magnets are composed of round pot magnet and one or more bolts.

     Advantages of pot magnet

1. Small size and stronger magnetic force

     The steel shell concentrates the magnetic force on one side and increases the pull to about 3 times of ordinary neodymium magnets. Compared with ordinary custom magnets, the same volume of the pot magnetic pull is stronger, and the same pull of the pot magnet’s volume is smaller.

2. Durability

     Since the neodymium magnet is very brittle, the outer steel will protect it, so there is no risk of the magnet breaking

3. A variety of installation methods

     The pot magnet generally has a center hole for bolts or screws to connect the magnet. In addition, it can be equipped with hooks to hang various items, and can also be added to the ring bolts for fishing magnets. Rubber-coated pot magnets are ideal for outdoor use and applications where surfaces are prone to damage.

4. Cost savings

     For a single ordinary strong magnet, the same volume of pot magnet not only has a stronger pull, but also uses less raw materials for rare earth neodymium magnets, thus reducing cost expenditures.

     Common applications of pot magnet

     The simple pot magnet is a popular magnetic component suitable for domestic or industrial usage. Such as, in daily life for lights, clocks, tool racks and other, pot magnet acts as magnetic base; In industrial activities for containers, multi-purpose trucks, delivery vans, displays, assembly lines and work tables, pot magnet is used as different installation options.
