FAQ
Q1. How do reverse magnetic fields inside a motor affect NdFeB magnets over time?
Reverse fields can cause gradual irreversible demagnetization if they exceed the intrinsic coercivity margin, especially at elevated temperatures. This effect is cumulative and often appears after long-term operation rather than during initial testing.
Q2. How close can operating load lines safely approach the knee of the demagnetization curve?
In practice, designs usually keep the load line at least 10–15% away from the knee under worst-case temperature and field conditions to ensure long-term stability.
Q3. Why do two magnets of the same grade show different demagnetization behavior in the same application?
Differences in grain alignment, local microstructure, coating integrity, and actual magnetization level can all influence real-world demagnetization performance.
