Dear Student,
◆ Answer -
μm = 6.915×10^-3 H/m
● Explanation -
Given that susceptibility of annealed iron at saturation is 5500. i.e. χ = 5500.
We have formula for magnetic permeability of material as -
μm = μ0 (1 + χ)
μm = 1.257×10^-6 (1 + 5500)
μm = 1.257×10^-6 × 5501
μm = 6.915×10^-3 H/m
Hence, the permeability of annealed iron at saturation is 6.915×10^-3 H/m.
Thanks dear. Hope this helps you...
