FAQ
Q1. 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.
Q2. How does thermal gradient inside the magnet affect stability?
Answer:Temperature gradients create uneven coercivity across the magnet. Hot spots may demagnetize locally even when average temperature remains within specification.
Q3. How do steel components influence effective coercivity?
Answer:Steel alters flux paths and can amplify local reverse fields. Improper steel design may unintentionally push magnet regions below safe operating points.
