Question

The magnetic susceptibility of a material of a rod is 499 . Permeability in vacuum is $4 \pi \times 10^{-7} \mathrm{H} / \mathrm{m}$. Absolute permeability of the material of the rod is:

Select the correct option:

$4 \pi \times 10^{-4} \mathrm{H} / \mathrm{m}$

$2 \pi \times 10^{-4} \mathrm{H} / \mathrm{m}$

$3 \pi \times 10^{-4} \mathrm{H} / \mathrm{m}$

$\pi \times 10^{-4} \mathrm{H} / \mathrm{m}$

✓ Correct! Well done.

✗ Incorrect. Try again or view the solution.

Solution

μ = μ₀ (1 + Xm) = 4π × 10⁻⁷ × 500 = 2π × 10⁻⁴ H/m
