FAQ
Q1. What causes irreversible demagnetization in NdFeB magnets?
Irreversible demagnetization can result from excessive temperature, strong reverse magnetic fields, improper magnetization direction, or mechanical stress during assembly and operation.
Q2. How do tolerance and machining accuracy affect magnet performance?
Tight dimensional tolerances are critical for air gap control and magnetic circuit efficiency. Excessive machining stress or improper grinding can also lead to microcracks and localized magnetic degradation.
Q3. What are the differences between sintered and bonded NdFeB magnets in performance?
Sintered NdFeB magnets offer significantly higher magnetic energy density and temperature resistance, while bonded NdFeB magnets provide better shape flexibility and isotropic magnetic properties but lower magnetic strength.
