FAQ
Q1.How do I select the correct NdFeB grade for my application?
Grade selection depends on required magnetic force, operating temperature, environmental conditions, and resistance to demagnetization. High-coercivity grades are recommended for elevated temperatures or dynamic magnetic fields.
Q2. What causes irreversible demagnetization in NdFeB magnets?
Irreversible demagnetization can occur due to excessive temperature, strong opposing magnetic fields, improper magnetization direction, or mechanical damage.
Q3. How much magnetic flux loss occurs at elevated temperatures?
Flux loss increases with temperature and varies by grade. While some loss is reversible, permanent loss may occur if the magnet exceeds its maximum operating temperature.
