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

$4 π \times 1 0^{- 4} H / m$

$2 π \times 1 0^{- 4} H / m$

$3 π \times 1 0^{- 4} H / m$

$π \times 1 0^{- 4} H / m$

$μ = μ_{0} (1 + x_{m})$
$= 4 π \times 1 0^{- 7} \times 500$
$= 2 π \times 1 0^{- 4} H / m$
