Magnetisation: B, H, M, χ & μ

A solenoid of 500 turns/m is carrying a current of 3 A. Its core is made of iron which has relative permeability 5001. The magnitude of magnetization is

Show answer and solution

Answer: (c)

  1. H=nI=500×3=1500 A m−1H = nI = 500 \times 3 = 1500\ \text{A m}^{-1}
  2. M=(μr−1)H=5000×1500=7.5×106 A m−1M = (\mu_r - 1)H = 5000 \times 1500 = 7.5 \times 10^{6}\ \text{A m}^{-1}
  3. So the answer is (c).
