    An iron rod of susceptibility 599 is subjected to a magnetising field of 1200 A m−1^{-1}. The permeability of the material is (μ0=4π×10−7\mu_{0} = 4\pi \times 10^{-7} T m A−1^{-1})

    Answer and explanation

    Answer: (4)

    Permeability is μ=μ0(1+χ)=4π×10−7×600=2.4π×10−4\mu = \mu_{0}(1 + \chi) = 4\pi \times 10^{-7} \times 600 = 2.4\pi \times 10^{-4} T m A−1^{-1}. Chapter: Magnetism and Matter.
