What is the Gauss of NdFeB N40?

1585792169699780 - What is the Gauss of NdFeB N40?

First of all, we can know from the N35 magnet that this is a NdFeB magnet, and its high temperature resistance is less than or equal to 80 ℃. Why? Because NdFeB magnets start with N, they are divided into N, m, h, SH, uh and eh grades. Each grade has different high temperature resistance. N40 is only one of the performance grades of NdFeB magnets, and 40 represents the maximum magnetic energy product. For magnets of the same specification, the larger the number after n means the stronger the magnetic force, and the more expensive the price is. N40 is a commonly used grade in the market.
What is the Gauss of NdFeB N40?
This problem has been introduced countless times before. The Gauss size of the magnet can not really reflect the real magnetic pull of the magnet. It is related to many factors such as the material, performance grade, size and thickness of the magnet. If you still want to know the Gauss size of the N40 magnet, I will give you a small part for your reference.

  • N40h / Ni / D4 * 1.8, magnetic field strength: 3160gs;
  • N40 / Ni / f25x17x3mm, magnetic field strength: 3200gs;
  • N40 / Ni / D6 * 3, measured magnetic 3220gs;
  • N40 / zinc / D70 * d30 * 3, surface magnetic 1020gs;
  • N40 / Zn / 18.2 * 8.1 * 4.7, surface magnetic 3260gs;
  • N40 ring / Ni / d22.23 * d4.76 * 25.44560gs.

The magnetic difference between N35 and N40 is still a little bit. You can choose conventional performance according to your needs. If you can’t meet the requirements, you can choose higher performance, such as N42, N45, N48, N50, etc.
