# The Susceptibility of Annealed Iron at Saturation is 5500. Find the Permeability of Annealed Iron at Saturation. - Physics

Sum

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

#### Solution

Susceptibility of annealed iron,

$\chi=5500$

The relation between permeability and susceptibility:-

Permeability, µ = µ0(1 + x)

µ = 4π × 10−7 (1 + 5500)

⇒ µ = 4 × 3.14 × 10−7 × 5501

⇒ µ = 69092.56 × 10−7

⇒ µ = 6.9 × 10−3
