Neodymium permanent magnets are strong magnets which consist of neodymium, iron, boron and a few transition metals. These magnets have metallic appearance and are found in simple shapes like rings, blocks and discs. The neodymium rare earth magnets are strong magnetically and are brittle in nature hence they must be handled with care. Since it is amenable to chipping and cracking it can be only be abrasively ground and that too along with the coolant. Due to their low cost they have successfully replaced heat resistant and marginally weaker magnets in various industrial applications.

Features of Sintered NdFeb Magnets

• Extreme strong Br Resident induction.
• Excellent demagnetization resistance capability
• Good Price relative to its high magnetic properties.
  
• Neodymium rare earth is prone to corrosion hence should be coated for long term maximum energy output.
  
  

Applications

The applications of the neodymium rare earth magnets are:

• They are used for stabilization and angular head motors in computer hard drives.
• They are also applicable in various earphones and headphones.
• Neodymium magnets have usage in various other industrial products like:
• Magnetic separators.
• Linear actuators.
• Microphone assemblies.
• DC motors.
• Printers.
• Speakers.
