Vedclass · Answer

(C) Given: $\mu_0 = 4 \pi 	imes 10^{-7} \ H/m$ and $\chi_m = 349$.The relationship between absolute permeability $\mu$,vacuum permeability $\mu_0$,and magnetic susceptibility $\chi_m$ is given by $\mu = \mu_0(1 + \chi_m)$.Substituting the values:$\mu = 4 \pi 	imes 10^{-7} 	imes (1 + 349)$$\mu = 4 \pi 	imes 10^{-7} 	imes 350$$\mu = 1400 \pi 	imes 10^{-7}$Using $\pi \approx 3.14159$:$\mu \approx 1400 	imes 3.14159 	imes 10^{-7}$$\mu \approx 4398.22 	imes 10^{-7} \ H/m$Rounding to the nearest significant value provided in the options,we get $\mu \approx 4400 	imes 10^{-7} \ H/m$.
