The magnetic susceptibility of the material of a rod is 349 and permeability of vacuum μ₀ is 4π × 10⁻⁷ SI units. Absolute permeability of the material of the rod in SI units is (a) 4400 × 10⁻⁷ (b) 4200 × 10⁻⁷ (c) 4800 × 10⁻⁷ (d) 4600 × 10⁻⁷

Answer: (a). μ = μ₀(1+χ) = 4π × 10⁻⁷ × 350 = 1400π × 10⁻⁷ ≈ 4400 × 10⁻⁷ SI units So the answer is (a).

The magnetic susceptibility of the material of a rod is 349 and permeability of vacuum $\mu_0$ is $4\pi \times 10^{-7}$ SI units. Absolute permeability of the material of the rod in SI units is

Show answer and solution

Answer: (a)

$\mu = \mu_0(1+\chi) = 4\pi \times 10^{-7} \times 350$
$= 1400\pi \times 10^{-7} \approx 4400 \times 10^{-7}$ SI units
So the answer is (a).
