The maxiumum value of the permeability of metal (77% Ni, 16% Fe, 5% Cu, 2% Cr) is `0.128 Tm A^(-1)`. Find the maxiumum relative permeability and susceptibility.

Explanation

To solve the problem of finding the maximum relative permeability and susceptibility of the given metal composition (77% Ni, 16% Fe, 5% Cu, 2% Cr) with a maximum permeability of \( \mu = 0.128 \, \text{Tm/A} \), we will follow these steps:

### Step 1: Identify the value of the permeability of free space (\( \mu_0 \))
The permeability of free space (\( \mu_0 \)) is a constant value given by:
\[ \mu_0 = 4\pi \times 10^{-7} \, \text{Tm/A} \]
