Question
The susceptibility of annealed iron at saturation is 5500. Find the permeability of annealed iron at saturation.
✓

Answer

Permiability $(\mu)=\mu_0(1+\text{x})$ Given susceptibility $= 5500$$\mu=4\times10^{-7}(1+5500)$
$=4\times3.14\times10^{-7}\times5501$
$= 6909.56\times10^{-7}\approx6.9\times10^{-3}$
