Rectangular Pot Magnets (Channel Magnets)

What is a Pot Magnet?

A pot magnet is made of a permanent magnet and a steel housing. Normally, pot magnets are round in shape with a disc magnet being embedded in the steel housing. These round based magnets are widely used in various holding applications because they provide an excellent holding force. 

The steel housing is made of ferromagnetic material that has high permeability and it can redirect the magnetic flux in a way that enhances the magnetic strength. The magnetic flux density becomes much denser on the working face of the pot magnets when compared to a stand-alone magnet with the same size and grade. In addition, pot magnets can be mounted on by various accessories such as hook, screw, eyelet, etc. to adapt themselves to various holding scenarios. Thus, they are also called mounting magnets.

Important Variation: Rectangular Pot Magnets (channel magnets)

Rectangular pot magnets are also known as channel magnets because of its channel-like steel housing. In most cases, the rectangular (or square) magnets are countersunk to make room for screws. Similar to round pot magnets, rectangular pot magnets can be fixed on a wall with its holding face staying outside. Tengye Magnetic manufactures neodymium magnets and stamped pot housing in-house. We can supply custom pot magnets.

We can supply screw along with the channel magnets. These channel magnets can also be mounted parallel to the ground for vertical holding applications.

Rubber Coated Pot Magnet

Rectangular pot magnets are also available with a rubber coating option. This rubber coating serves as a protective layer, guarding sensitive surfaces like painted ones from potential scratches. Additionally, the rubber coating enhances the magnet’s grip when used in vertical orientations, thanks to its increased friction.
