FAQ
Q1. How is irreversible demagnetization tested in NdFeB magnets?
Irreversible demagnetization is evaluated by exposing magnets to elevated temperatures and external demagnetizing magnetic fields. Magnetic properties are measured before and after testing to quantify permanent flux loss and ensure compliance with application requirements.
Q2. How do you verify intrinsic coercivity (Hcj) stability?
Intrinsic coercivity is verified using hysteresis loop measurements conducted before and after thermal aging, temperature cycling, and magnetic field exposure to ensure long-term resistance to demagnetization.
Q3. How is magnetic aging performance evaluated?
Magnetic aging is assessed through long-term high-temperature storage tests, typically ranging from 500 to 1,000 hours. Magnetic flux loss is monitored periodically to confirm performance stability over the expected service life.
