PhysicsSingle correct+4 / -1Question 40 of 90

The susceptibility of a paramagnetic material is 99. The permeability of the material in Wb/A-m, is :

[Permeability of free space $\mu_0=4\pi\times10^{-7}$ Wb/A-m]

4\pi\times10^{-7}

4\pi\times10^{-4}

4\pi\times10^{-5}

4\pi\times10^{-6}

Answer and worked solution

Official answer: C

Permeability. $\mu=\mu_0(1+\chi)=100\times4\pi\times10^{-7}=4\pi\times10^{-5}$ Wb/A-m.

(C)
