Neodymium Channel Magnet

Channel Magnet Supplier

Neodymium channel magnet gets its name exactly from its structure, which is characterized by mounting holes on various surfaces.

Neodymium channel magnets are stronger than ceramic channel magnets or standard neodymium block/rod shapes because the steel channel concentrates most of the magnetic field on one side of the magnet. They are plated with three layers of Ni-Cu-Ni and use an electrolytic process for maximum protection against oxidation and corrosion.

Neodymium channel magnets can be used in both indoor & outdoor applications, they are ideal for industrial & consumer mounting holding & fixing applications where high-magnetic strength is required.

Dongguan KENENG International Trading Co., Ltd has strictly QC from raw materials to output products, which is a channel magnet supplier in China. We have MSDS /ROHS/REACH/ISO 9001 certificates and have 15 years experiences in neodymium channel magnets design and manufacturing. We have won good reputation in this industry for our excellent and stable quality, prompt delivery and fast response .

Custom Neodymium Channel Magnet

We can custom neodymium channel magnet. Non-standard magnet products can be processed and customized according to customers’ requirements. Our Neodymium and Ferrite channel magnets are encased within a secure steel shell, with either countersunk or through-hole fixing and are extremely versatile for use in mounting or securing, in door latches and for holding signage and banners.

Our neodymium channel magnets are sintered for optimal magnetic strength and axially magnetized (the magnetism direction is along the axis of the magnet from the north to the south poles).

See the below drawing for your reference.

Types of Custom Neodymium Channel Magnet

NdFeB channel magnets have a through hole in the center, which makes it easy to fasten the magnet where high holding force is required.

The channel magnet is named for its structure. Its working principle of it is the same as that of the round can magnet. It conducts the magnetic field strength through the steel groove, so that the holding surface has an alternating pole pattern, so as to obtain a higher holding force.

KENENG is a professional manufacturer of single-sided magnet, rubber magnet, ferrite black magnet, ring strong magnet, circular strong magnet, square strong magnet, screw hole strong magnet, straight hole strong magnet, countersunk strong magnet, strip strong magnet, trapezoidal strong magnet, special-shaped strong magnet, and so on, and has a complete and scientific quality management system. Our company is recognized by the industry for its integrity, strength and product quality.

If you need to custom neodymium channel magnets, you can choose different materials(except neodymium, you can also choose ferrite), size, finishing, etc. The specific parameters you can choose include:


  • Ferrite
  • Neodymium
  • with steel tank


  • * As per customers’ requirements.

  • Plating (Zn, Ni,Cu)
  • Black powder coat


  • Channel magnets can be used in indoor and outdoor applications, suitable for industrial and consumer mounting applications that require high magnetic strength, such as rails that can be used for letterpress printing and commercial sewing, for door latches, additional identification or simple tool storage.
  • These magnets come with countersink holes which will allow them to fit screws and nuts bolts in them.
  • Neodymium channel magnets are also used in the manufacturing of the hard disk drives used in computers.  
  • These magnets are also widely used in electronic equipment like Sound mic, Headphones, loudspeakers, etc.
  • Electric motors use neodymium magnets to convert the electrical energy into mechanical energy whereas the electric generator uses the same magnet to convert mechanical energy into electrical energy.
  • Other than that, neodymium magnets are also used in medical applications like MRI scans, magnetic medical therapies, etc.


  • Super magnetism: magnetism is limited to one surface, on which the magnetism is concentrated.
  • Not fragile: The channel magnet will not produce fragments or cracks when constantly impacting the steel surface, which is another great advantage.

FAQ of Neodymium Channel Magnet

We all know that since it is magnetic, it can function conveniently. So they have a constitution like now, it has important chemistry. What should be paid attention to today with strong magnets?

How to store neodymium magnets safely?

1. NdFeB magnets should not be close to electronic equipment, because the magnet itself has positive and negative poles and circuit circuits, which will affect the use of electronic equipment and control circuits.

2. Do not store the magnet in a humid environment to avoid oxidation, resulting in changes in appearance, physical properties and magnetic properties.

3. Do not place magnets near floppy disks, hard drives, credit cards, magnetic tapes, record cards, TV picture tubes, etc. If magnets are placed near devices such as magnetic recorders, the recorded data can be affected or even destroyed.

4. Do not store or use magnets above the Curie temperature (neodymium magnets 590°F) to avoid demagnetization.

5. Because the magnetic force is too strong, it is necessary to do a good job of magnetic isolation.

6. Keep it out of reach of children and pets, and lock it if necessary.

  • Vehicle license plate holders
  • Blueprint holders
  • Sign and banner holders

The strength of the channel assembly is 32 times that of the ceramic magnet itself. The tensile strength is tested on a 3/8 inch thick steel plate. The tension may vary according to the surface it is attracted to, for example, if the steel is less than 3/8 inch thick, coated, rough or rusty. We recommend that you get a sample to test and confirm the actual pull / hold ability when using in your application.

The powerful neodymium magnet is embedded in the U-shaped steel profile. If the magnet directly contacts the surface of thick iron, the steel will enhance the adhesion of the magnet. If there is no direct contact with the corresponding object, or when the iron sheet is thin, painted or rough, the adhesion of the magnet is much weaker.
