At this stage, the strongest permanent magnets on the market are neodymium magnets, also known as NdFeB magnets. Usually, NdFeB magnets refer to NdFeB magnets, the higher the grade of NdFeB magnets, the higher the magnetic force, the strongest model is N55.SourceRare earth magnet-https://www.rare-earthmagnet.com/strongest-magnet/

The selection of neodymium magnet is usually based on the use scenario of the product, in general environment, the higher the model number of the same specification, the higher the magnetic force, the highest temperature of N model is 80 degrees.SourceRare earth magnet-https://www.rare-earthmagnet.com/strongest-magnet/

Here is the issue of permanent magnet model.SourceRare earth magnet-https://www.rare-earthmagnet.com/strongest-magnet/

N: general coercive force Hcj ≥ 12 Koe, such as: N40 (maximum ambient temperature of 80 ° C)SourceRare earth magnet-https://www.rare-earthmagnet.com/strongest-magnet/

M: medium coercivity Hcj ≥ 14 Koe, such as: 48M (maximum ambient temperature of 100°C)SourceRare earth magnet-https://www.rare-earthmagnet.com/strongest-magnet/

H: higher coercivity Hcj ≥ 17 Koe, such as: 45H0 (maximum ambient temperature of 120°C)SourceRare earth magnet-https://www.rare-earthmagnet.com/strongest-magnet/

SH: ultra-high coercivity Hcj ≥ 20 Koe, such as: 42SH (maximum ambient temperature of 150°C)SourceRare earth magnet-https://www.rare-earthmagnet.com/strongest-magnet/

UH: very high coercivity Hcj ≥ 25 Koe, such as: 38UH (maximum ambient temperature of 180 ° C)SourceRare earth magnet-https://www.rare-earthmagnet.com/strongest-magnet/

EH: extra-high coercivity Hcj ≥ 30 Koe, such as: 35EH (maximum ambient temperature of 200 ° C)SourceRare earth magnet-https://www.rare-earthmagnet.com/strongest-magnet/

AH: ultra-high coercivity Hcj ≥ 35 Koe, such as: 28AH (maximum ambient temperature 230°C)SourceRare earth magnet-https://www.rare-earthmagnet.com/strongest-magnet/

"T": indicates magnets with corrosion resistance requirements, such as: N45TSourceRare earth magnet-https://www.rare-earthmagnet.com/strongest-magnet/

"L-T": the table indicates that the low temperature coefficient, and corrosion resistance requirements of the magnet, such as: L-38SHSourceRare earth magnet-https://www.rare-earthmagnet.com/strongest-magnet/

Many people think that the magnetic force of permanent magnets with H, SH and so on after the model number will be stronger, but in fact it is not, it only means that these are high temperature resistance, the higher the temperature resistance, the lower the magnetic force actually is.SourceRare earth magnet-https://www.rare-earthmagnet.com/strongest-magnet/

What is the magnetic power of NdFeB magnet related to?SourceRare earth magnet-https://www.rare-earthmagnet.com/strongest-magnet/

 SourceRare earth magnet-https://www.rare-earthmagnet.com/strongest-magnet/

The magnetic strength of NdFeB magnets is related to the raw material, the direction of magnetization, the temperature of the environment and the size of the magnets.SourceRare earth magnet-https://www.rare-earthmagnet.com/strongest-magnet/

The higher the size of NdFeB magnet, the higher the magnetic force. The NdFeB magnet is very easy to demagnetize or completely demagnetize in the environment that is larger than the maximum ambient temperature.SourceRare earth magnet-https://www.rare-earthmagnet.com/strongest-magnet/
