We know μ =(μ )0(1 + X) ⇒ μ =500× 4π × 10- 7 ⇒ μ =2π × 10- 4Hm- 1

Q. The magnetic susceptibility of a material of a rod is $499$ . Permeability of vacuum is $4 π \times 1 0^{- 7} H m^{- 1}$ . Absolute permeability of the material of the rod in $H m^{- 1}$ is

$π \times 1 0^{- 4}$

$2 π \times 1 0^{- 4}$

$3 π \times 1 0^{- 4}$

$4 π \times 1 0^{- 4}$

We know
$μ = (μ)_{0} (1 + X)$
$\Rightarrow μ = 500 \times 4 π \times 1 0^{- 7}$
$\Rightarrow μ = 2 π \times 1 0^{- 4} H m^{- 1}$
