FAQ
Q1. How does the knee point of the demagnetization curve affect real operating safety?
Answer:The knee point defines where irreversible demagnetization begins. Operating too close to the knee-especially under temperature or reverse-field stress-can cause permanent performance loss. Safe designs maintain sufficient margin between the working point and the knee across all conditions.
Q2. Why do magnets with high Hcj still demagnetize in certain assemblies?
Answer:High Hcj alone does not guarantee stability. Local reverse fields, flux concentration at edges, sharp corners, and poor magnetic circuit design can exceed local coercivity, leading to partial demagnetization despite high material ratings.
Q3. How does internal magnetic field distribution differ from surface flux measurements?
Answer:Surface flux density reflects only external field strength. Internal field distribution determines true stability and demagnetization risk, which may not be detectable without simulation or destructive testing.
