FAQ

Q1. What is the difference between intrinsic coercivity (Hcj) and coercivity (Hcb)?

Answer:Hcj represents the magnet's resistance to irreversible demagnetization, while Hcb indicates resistance to partial demagnetization. Hcj is more critical for applications involving high temperature, vibration, or opposing magnetic fields, as it better reflects long-term magnetic stability.

Q2. Why does a higher grade NdFeB magnet sometimes perform worse at elevated temperatures?

Answer:Higher grades offer higher magnetic energy at room temperature but often have lower intrinsic coercivity. Without proper temperature grading (H, SH, UH, etc.), high-grade magnets may suffer irreversible demagnetization when exposed to heat.

Q3. How does magnet thickness influence demagnetization risk?

Answer:Thicker magnets provide better internal magnetic stability and are less susceptible to demagnetization. Thin magnets operating near their temperature limit or in open magnetic circuits face a higher risk of performance loss.
