Question

The magnetic field b and the magnetic intensity h in a material are found to be 1.60 and thousand eight respectively

Answer 1

B = 1.6 T, H = 1000 A/m μ = Permeability of material μ = B/H = 1.6/1000 = 1.6 x 10^-3 μ = μ/ μ base 0 = 1.6x 10^-3 / 4π x 10^-7 = 0.127 x 10^4 ≈ 1.3 x 10^3 μ = μ base 0 (1 + x) ⇒ X = μ/ μ base 0 -1 = μr – 1 = 1.3 × 10^3 – 1 = 1300 – 1 = 1299 ≈ 1.3 × 10^3
