Question

The magnetic susceptibility of a material of a rod is 499 . The absolute permeability of vacuum is 4 π × 10 - 7 H m - 1 . The absolute permeability of the material of a rod is, π × 10 - 4 H m - 1, 2 π × 10 - 4 H m - 1, 3 π × 10 - 4 H m - 1, 4 π × 10 - 4 H m - 1

MARKS App · Accepted Answer

Absolute permeability of material of rod μ = μ r μ 0 = 1 + X m μ 0 ∴ μ = 1 + 499 × 4 π × 10 - 7 = 2 π × 10 - 4 H m - 1
