The magnetic susceptibility of the material of a rod is 499. Permeability of vacuum is $4\pi × 10^{-7} H/m$. The absolute permeability of the material of the rod is |
$4π × 10^{-4} H/m$ $π × 10^{-4} H/m$ $2π × 10^{-4} H/m$ $3π × 10^{-4} H/m$ |
$2π × 10^{-4} H/m$ |
The correct answer is Option (3) → $2π × 10^{-4} H/m$ |
