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

Explanation

To find the permeability of annealed iron at saturation, we can follow these steps:

### Step 1: Understand the relationship between permeability and susceptibility
The permeability (μ) of a material is related to its magnetic susceptibility (χ) by the formula:
\[ \mu = \mu_0 (1 + \chi) \]
where:
- \( \mu_0 \) is the permeability of free space (vacuum), approximately \( 4\pi \times 10^{-7} \, \text{T m/A} \)
- \( \chi \) is the magnetic susceptibility of the material.
