FAQ
Q1. Should magnets be magnetized before or after assembly?
Post-assembly magnetization is preferred for complex assemblies to reduce handling risks and assembly forces, but it requires suitable fixtures and magnetizing equipment. Pre-magnetization is simpler but increases assembly difficulty and safety risks.
Q2. What risks exist when magnetizing thin or ring-shaped magnets?
Thin sections are more prone to cracking during magnetization due to mechanical stress and uneven field distribution. Ring magnets may suffer from incomplete or non-uniform magnetization if fixture design is inadequate.
Q3. How are Br, Hcj, and BHmax typically verified in production?
They are measured using hysteresis graphs (BH curve testers) on sample coupons, while flux consistency is often monitored using Helmholtz coils or flux meters for 100% or statistical inspection.
