FAQ
Q1.What is Br, Hcj, and (BH)max?
Br (Residual Flux Density): Indicates the magnetic strength remaining after magnetization.
Hcj (Intrinsic Coercivity): Measures resistance to demagnetization, especially important for high-temperature or dynamic applications.
(BH)max (Maximum Energy Product): Represents the magnet's maximum magnetic energy density.
Q2. How does temperature affect NdFeB magnet performance?
Rising temperature reduces magnetic flux. Selecting a magnet with sufficient coercivity margin is essential to avoid irreversible demagnetization under operating conditions.
Q3. What is irreversible vs. reversible demagnetization?
Reversible demagnetization recovers when temperature returns to normal.
Irreversible demagnetization causes permanent loss of magnetic performance and must be avoided through proper grade selection.
