NdFeB Ring Magnet

NdFeB Ring Magnet

The NdFeB Ring Magnet is a high-performance neodymium magnet shaped like a ring, offering powerful magnetic strength and versatility. Made from neodymium, iron, and boron (NdFeB), it provides one of the strongest magnetic forces available in permanent magnets, making it ideal for applications requiring high holding power in a compact form. The ring shape allows for easy mounting onto shafts or rods, commonly used in motors, generators, and magnetic assemblies. This type of magnet is widely applied in industries such as automotive, electronics, and renewable energy, where strong, durable magnets are essential for efficient operation and performance.

 Product Details 

What grades & shapes are available for neodymium magnets?

Grades N35, N38, N40, N42, N48, N50, and N52 ( M, H, SH, UH, EH, AH series ) are available for all shapes & sizes of NdFeB magnets.

  Magnetization Direction 

Common direction of magnetization showed in picture bellow: 

• Disc, cylinder and Ring shape magnet can be magnetized Axially or Diametricall.
• Rectangle magnets can be magnetized through Thickness, Length or Width.
• Arc shape magnets can be magnetized Diametrically, through Width or Thickness.

   Axially Magnetized                 Diametrically Magnetized                  Multi-poles Axially                  Multi-poles Diametrically

 Grade & Coating 

Support all magnet plating , like Ni-Cu-Ni, Zn, Epoxy , Gold,  Silver etc.

• Neodymium magnets are made of Neodymium, Iron and Boron.  If left to the elements, the iron in magnet will rust.

To protect the magnet from corrosion and to strengthen the brittle magnet material, it is usually preferable for the magnet to be coated.

• There are a variety of options for coatings, but nickel is the most common and usually preferred. 

Our nickel plated magnets are actually triple plated with layers of nickel, copper, and nickel again. This triple coating makes  magnets much more durable than the more common single nickel plated magnets.

• Other options of coating are zinc, tin, copper, epoxy,silver and gold.

 Application 

The Round Neodymium Magnet Ring is widely used in various applications due to its strong magnetic force and ring shape. It's commonly utilized in motors, sensors, and magnetic couplings, where precise alignment and rotation are required. Additionally, it's ideal for use in loudspeakers, where it helps create high-quality sound by interacting with the voice coil. 

The central hole allows for easy mounting on rods or shafts, making it perfect for industrial machinery, medical devices, and other precision engineering applications.
