Tags: NdFeB magnet, neodymium disc magnet, N38 magnet, strong magnet

This product is a circular NdFeB neodymium disc magnet with a diameter of 8mm and a thickness of 2mm, graded N38. It is made from a neodymium-iron-boron alloy with a crystalline structure of Nd₂Fe₁₄B. The magnet features a triple-layer nickel-copper-nickel (Ni-Cu-Ni) coating, which provides high resistance to corrosion and moisture while extending its service life. The maximum operating temperature of this magnet is 80°C.

Working Principle and Key Considerations

Neodymium magnets are the strongest type of permanent magnet commercially available. Below 150°C, NdFeB is recognized as the strongest magnet in the world. The N38 grade indicates the quality of the magnetic material; the higher the number following the letter N, the stronger the magnet and the higher its operating temperature. This magnet is used in a wide range of applications, including generators, electric motors, sensors, magnetic suspension systems, microphones and headphones, magnetic separators, computer hard disk drives, magnetic bearings, magnetic clamps, and ABS systems. Note that the magnet is brittle due to the nickel alloy used, and exposure to high temperatures will cause it to lose its magnetic properties.

Neodymium Magnet Applications:

  1. Generators
  2. Advanced audio equipment
  3. MRI equipment
  4. Precision instruments
  5. Automotive oil filters
