Magnetisation: B, H, M, χ & μ

The susceptibility of a paramagnetic material is 99. The permeability of the material in Wb/A-m, is: [Permeability of free space μ\mu0 = 4π×\pi \times 10−-7 Wb/A-m]

Show answer and solution

Answer: (c)

  1. μr=1+χ=100\mu_r = 1 + \chi = 100
  2. μ=μrμ0=100×4π×10−7=4π×10−5 Wb/A-m\mu = \mu_r\mu_0 = 100\times4\pi\times10^{-7} = 4\pi\times10^{-5}\text{ Wb/A-m}
  3. So the answer is (c).
