Magnetisation: B, H, M, χ & μ

A solenoid having 400 turns per metre has a core of a material with relative permeability 400. When a current of 0.5 A is passed through it, the magnetization of the core material in Am−1\text{Am}^{-1} is nearly

Show answer and solution

Answer: (d)

  1. H=nI=400×0.5=200 A m−1H = nI = 400 \times 0.5 = 200\ \text{A m}^{-1}
  2. M=χH=(μr−1)H=399×200≈8×104 A m−1M = \chi H = (\mu_r - 1)H = 399 \times 200 \approx 8 \times 10^{4}\ \text{A m}^{-1}
  3. So the answer is (d).
