1.	The maximum value of the permeability of `mu` metal (77% Ni, 16% Fe, 5% Cu, 2% Cr) is `0.128 Tm A^(-1)`. Find the maximum relative permeability and susceptibility.
Answer» Correct Answer - `mu_r=10xx10^5`; `chi=10xx10^5` Here, `mu=0126TmA^-1` `:. mu_r=(mu)/(mu_0)=(0126)/(4pixx10^-7)=10xx10^5` Max. susceptibility `chi=mu_r-1=10xx10^5-1` `=1*0xx10^5`
