The permeability can be calculated using the formula:

Permeability = Susceptibility * (4π * 10^-7)

Given that the susceptibility of annealed iron at saturation is 5000, the permeability is:

Permeability = 5000 * (4π * 10^-7)
Permeability ≈ 2.257 x 10^-2

Therefore, the permeability of annealed iron at saturation is approximately 2.28.

µr = 1 + χ
= 1 + 5000
= 5001
∵ μ = μrμ0 = 5001 (4π x 10-7)
