The magnetic susceptibility of a material of a rod is 299. Permeability of vacuum μ₀ is 4πx10⁻⁷ Hm⁻¹. Absolute permeability of the material of the rod is
Options
(a) 3771×10⁻⁷ Hm⁻¹
(b) 3771×10⁻⁵ Hm⁻¹
(c) 3771×10⁻⁶ Hm⁻¹
(d) 3771×10⁻⁸ Hm⁻¹
Correct Answer:
3771×10⁻⁷ Hm⁻¹
Explanation:
Then given, χ(m) = 299, μ₀ = 4π × 10⁻⁷ Hm, and μ = ?
We know that, μ = μ₀ [1 + χ(m)]
μ = 4π × 10⁻⁷ (1 + 299) = 4 × (22/7) × 10⁻⁷ × 300
= [2.6400 / 7] × 10⁻⁷
= 3771.4 × 10⁻⁷ Hm⁻¹ (or),
≃ 3771 × 10⁻⁷ Hm⁻¹
