Q.
What is hysteresis material constant ηB?
- Ferrites and Accessories >
- Ferrite Cores
A. It is a constant that represents hysteresis loss when a magnetic material is operating in the Rayleigh region, as shown in the following formula.
Here:
- tanδh : Hysteresis loss coefficient
- μ : Relative permeability in the Rayleigh region
- Bm : Maximum magnetic flux density (T)
