FAQ
Q1. What causes localized demagnetization rather than uniform loss?
Answer:Localized demagnetization occurs due to non-uniform reverse fields, temperature gradients, or geometric stress points. These localized losses often degrade system performance before global magnet weakening is detected.
Q2. How does magnetization field strength relate to full saturation?
Answer:Insufficient magnetizing field results in incomplete domain alignment. Full saturation requires magnetizing fields significantly higher than intrinsic coercivity, especially for high-Hcj grades.
Q3. Why does radial magnetization exhibit higher field deviation risk?
Answer:Radial magnetization relies on complex tooling and precise field symmetry. Small tooling or alignment errors cause angular field distortion, which directly affects motor efficiency and sensor accuracy.
