An iron bar having a cross sectional area of 2 \times 10^{-5} {m}^2 and magnetising field of 2400 {A} \/ {m} produce a magnetic flux of 2.4 \pi \times 10^{-5} {Wb}. What will be the value of permeability (\mu) and susceptibility (\chi) of the bar (Given \mu_0=4 \pi \times 10^{-7} )

Correct Answer is : µ=5π×10−4,χ=1249

\mu=5 \times 10^{-4}, \chi=1249 \pi

\mu=5 \pi \times 10^{-4}, \chi=1249 \pi

\mu=5 \pi \times 10^{-4}, \chi=1249

\mu=5 \times 10^{-4}, \chi=1249

An iron bar having a cross sectional area of 2×10−5m2 and magnetising field of 2400A∕m produce a magnetic flux of 2.4π×10−5Wb. What will be the value of permeability (µ) and susceptibility (χ) of the bar (Given µ0=4π×10−7 )

µ=5×10−4,χ=1249π
µ=5π×10−4,χ=1249π
µ=5π×10−4,χ=1249
µ=5×10−4,χ=1249
