Magnetisation: B, H, M, χ & μ

The magnetic susceptibility of the material of a rod is 599. The absolute permeability of the material of the rod will be [ $\mu_0 = 4\pi \times 10^{-7}$ SI unit]

Show answer and solution

Answer: (b)

$\mu = \mu_0 \mu_r = \mu_0(1+\chi)$
$\mu = 4\pi \times 10^{-7} \times 600 = 2400\pi \times 10^{-7} = 2.4\pi \times 10^{-4}$ SI units
So the answer is (b).
