Calculate permeability and susceptibility of a magnetic bar of cross-section `0*1cm^2` having magnetic flux of `2*41xx10^-5Wb` due to magnetic intensity of `3200Am^-1`.

Answer

`7*53xx10^-4Tm A^-1`; `596*1`

Explanation

Here, `A=0*1cm^2=0*1xx10^-4m^2, mu=?, chi_m=?`
`phi=2*41xx10^-5Wb`,
`H=3200Am^-1`
`mu=B/H=(phi//A)/(H)=(phi)/(AH)=(2*41xx10^-5)/(0*1xx10^-4xx3200)`
`=7*53xx10^-4TmA^-1`
`chi_m=mu_r-1=(mu)/(mu_0)-1=(7*53xx10^-4)/(4pixx10^-7)-1`
`chi_m=597*1=596*1`
