The magnetic properties of Sintered NdFeB magnets can last long

Third, the magnetic properties of Sintered NdFeB magnets can last long?

Sintered NdFeB magnetss have a very high coercivity, the natural environment and general conditions do not appear demagnetization magnetic field and the magnetic variation. Assuming proper environment, even after prolonged use, the magnets can damage will not be great. Therefore, in practical applications, we tend to ignore the time factor on the magnetic properties.

Four on the orientation direction

Orientation direction: get the best magnetic anisotropic magnetic direction as the direction of magnetic orientation. Magnet divided into: 1, isotropic magnets: are the same in any direction of the magnet magnetic

2, anisotropic magnets: in different directions have different magnetic properties;, and there is a direction that alignment direction is oriented in the direction of the resulting magnetic highest magnets. Sintered Sintered NdFeB magnetss are anisotropic, and thus need to determine the orientation direction of the pre-production (magnetization direction).

Five factors that affect the magnetic Sintered NdFeB magnetss?

Ambient temperature, because the temperature Sintered NdFeB magnets work extremely sensitive to the environment and sustainable instantaneous maximum temperature maximum temperature may be magnets produce different degrees of demagnetization, including reversible and irreversible, recoverable and non-recoverable.
