The magnetic susceptibility of a material of a rod is 499. Permeability in vacuum is 4$\pi$ $\times$ 10$-$7 H/m. Absolute permeability of the material of the rod is :
Solution
$\mu$ = $\mu$<sub>0</sub> (1 + x<sub>m</sub>)<br><br>= 4$\pi$ $\times$ 10<sup>$-$7</sup> $\times$ 500<br><br>= 2$\pi$ $\times$ 10<sup>$-$4</sup> H/m
