How do you find permeability from B-H curve?

Answer 1

Permeability can be determined from the B-H curve by calculating the slope of the curve in the linear region, where the relationship between magnetic flux density (B) and magnetic field strength (H) is approximately linear. The permeability (μ) is defined as the ratio of B to H (μ = B/H). In practice, one can take the values of B and H from the linear portion of the curve and use them to calculate the permeability at that specific point. Additionally, the initial permeability can be assessed by evaluating the slope at the origin of the B-H curve.
