N52 Permanent Neodymium Disc Magnets

A Neodymium magnet, also known as NdFeB or Neo magnet, is the strongest known type of permanent magnet. Because of their lightweight, strength and the consistency of their magnetization, Neodymium Magnets have become a popular choice for a wide variety of applications, from loudspeakers to magnetic therapy jewelry.

Neodymium disc magnets

Rare Earth Disc Magnets, also called disc neodymium magnets, are the perfect marriage of small size and maximum power

or strength. Bearheart magnet provides a large variety of Neodymium disc magnets in a variety of sizes and with several
coatings such as Nickel, zinc or Gold for protection against corrosion.

N52 strong neodymium disc magnets

Features include
Neodymium magnets are the most powerful commercially produced magnets.
Neo magnets are hard and brittle and may chip or break if dropped.
Neodymium disc magnets are magnetized through the thickness.
Uncoated NdFeB magnets may corrode in humid conditions.
Operating temperatures vary among material grades. 

For a comparison of neodymium material grades, please see our chart of material properties.

Neodymium Magnet Applications

Neodymium magnets have replaced Alnico and ferrite magnets in many applications where strong permanent magnets are required, because their greater strength allows the use of smaller, lighter magnets. These applications include:

  • package closures
  • displays and signs
  • head actuators for computer hard disks
  • magnetic resonance imaging (MRI)
  • magnetic guitar pickups
  • loudspeakers and headphones
  • magnetic bearings and couplings
  • permanent magnet motors
  • cordless tools
  • servo motors
  • lifting and compressor motors
  • synchronous motors
  • spindle and stepper motors
  • electrical power steering
  • drive motors for hybrid and electric vehicles actuators
