The susceptibility of a paramagnetic material is 9999. The permeability of the material in Wb/A−mWb / A - m, is [Permeability of free space μ0=4π×10−7Wb/A−m{\mu}_{0} = 4\pi \times {10}^{- 7}Wb / A - m]

Options

  1. A4π×10−54\pi \times {10}^{- 5}
  2. B4π×10−64\pi \times {10}^{- 6}
  3. C4π×10−74\pi \times {10}^{- 7}
  4. D4π×10−44\pi \times {10}^{- 4}

Correct answer

A. 4π×10−54\pi \times {10}^{- 5}

Step-by-step solution

Using the relation of magnetic susceptibility (χ)\left(χ\right) and relative permeability\left({\mu}_{r}\right).</p><p>.</p><p>{\mu}_{r} = 1 + χ = 1 + 99 = 100</p><p>Magneticpermeability,</p><p>Magnetic permeability,\mu = {\mu}_{0}{\mu}_{r}</p><p></p><p>= 4\pi \times {10}^{- 7} \times 100</p><p></p><p>\mu = 4\pi \times {10}^{- 5}
