What are Neodymium Ring Magnets?

Neodymium ring magnets are powerful rare earth magnets made from an alloy of neodymium, iron, and boron. These magnets are particularly suited for applications requiring strong magnetic fields and compact sizes.

Advantages
  • Exceptional Strength: Neodymium magnets are the strongest commercially available magnets.
  • Versatility: Suitable for a wide range of advanced applications.
  • Affordability: Cost-effective due to advancements in manufacturing processes.
  • High Magnetic Properties: Strong holding and magnetic force due to their high remanence and energy product.
  • Hard and Brittle: Prone to chipping and breaking if not handled carefully.
  • Magnetization: Typically (with some exceptions) ring magnets are magnetized through the thickness.
  • Corrosion Resistance: Uncoated magnets may corrode in humid conditions.
  • Temperature Tolerance: Operating temperatures vary by material grade.

Neodymium ring magnets are used in:

  • Modern motors
  • Generators
  • Hydraulic cylinders
  • Pumps
  • Sensors
  • High-end loudspeakers
  • High-intensity separators

Specifications

Dimensions are listed in inches. All rings listed are supplied magnetized through the thickness. Additional sizes, plating options, magnetization methods and grade choices are also available upon request and may be on hand from stock.
