Question

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

Answer 1

Permeability $\left(\mu \right)={\mu }_0(1+x)$

Given

Susceptibility = 5500

$\mu =4\pi \times {10}^{-7}\times 5501$

= $69095.6\times {10}^{-7}$

= $6.9\times {10}^{-3}$
