The susceptibility of annealed iron at saturation is 5500. Find the permeability of annealed iron at saturation.
Ans : Susceptibility of annealed iron, `` \chi `` = 5500
The relation between permeability and susceptibility:
Permeability, µ = µ₀(1 + x)
µ = 4`` \,\mathrm{\,\pi \,}`` × 10^-7(1 + 5500)
`` \Rightarrow `` µ = 4 × 3.14 × 10^-7 × 5501
`` \Rightarrow ``µ = 69092.56 × 10^-7
`` \Rightarrow ``µ = 6.9 × 10^-3
