Rare Earth Magnets Info

Rare Earth Magnets are found in many of today’s technology and industrial applications as well as being popular with hobbyists, Arts and Crafts persons, and DIYers. Their popularity is based on strength, size, and affordability.

What are Rare Earth Elements?

Contrary to the name, the Rare Earth Elements used are relatively abundant on Earth. However, they are rarely found in concentrated deposits, but instead are found dispersed among other elements throughout the earth’s crust.

The extraction process to remove the elements comes with a high cost in terms of expense, effort, and environmental impact. Currently, China is the main source of rare earth elements – producing more annually than the rest of the world combined.

What Are Rare Earth Magnets Made Of?

Rare Earth Magnets are composed of two different type: Neodymium Magnets and Samarium Cobalt (SmCo) Magnets. Both types of magnets come in various grades ranging from N35 to N52, however they each have different magnetic and physical properties. Choosing the right rare earth magnet will be based on the project’s requirements.

Neodymium Magnets

Neodymium Magnets, the stronger of the two types of magnets, are composed of alloys containing neodymium, iron and boron – and are brittle and vulnerable to corrosion. These magnets are typically plated with nickel to help prevent oxidation.


  • Strongest magnet for its size
  • High coercive force
  • Very high resistance to demagnetization


  • Brittle
  • Low corrosion resistance
  • Moderate Temperature stability depending on the grade

Common Uses for Neodymium Magnets:

  • Medical devices
  • Linear actuators
  • Servo motors
  • Magnetic separators
  • Computer printers, disc drives, and speakers
  • Microphones
  • DC motors
  • Purse closures and clasps
Samarium Cobalt Magnets

Samarium Cobalt Magnets are made of samarium, cobalt and iron. They are typically difficult to demagnetize, have relatively high operating temperatures, and they have a high resistance to corrosion. They can also be coated.


  • High resistance to corrosion
  • High temperature stability
  • High resistance to demagnetization


  • Higher cost
  • Brittle

Common Uses for Samarium Cobalt (SmCo) Magnets:

  • Computer disk drives
  • Traveling Wave Tubes
  • Linear actuators
  • Satellite systems
  • Remote control race cars
  • Marine applications
  • Motor filtration
  • Purse closures and clasps
