Hysteresis material constant ηB is a constant that represents hysteresis loss when a magnetic material is operating in the Rayleigh region, as shown in the following formula:
- tanδh: Hysteresis loss coefficient
- μ: Relative permeability in the Rayleigh region
- Bm: Maximum magnetic flux density (T)
