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

`mu_r=1*0xx10^5`; `chi=1*0xx10^5`

Explanation

Here, `mu=0*126TmA^-1`
`:. mu_r=(mu)/(mu_0)=(0*126)/(4pixx10^-7)=1*0xx10^5`
Max. susceptibility `chi=mu_r-1=1*0xx10^5-1`
`=1*0xx10^5`
