Magnetic susceptibility of ferromagnetic material

The relative permeability of a ferromagnetic material is \( 5999 \). Its magnetic susceptibility is
\( 6000 \)
\( 6000 \times 10^{-7} \)
\( 5998 \)
\( 5.999 \times 10^7 \)

Solution:

The relation between relative permeability and magnetic susceptibility is \( \mu_r = 1 + \chi_m \). Therefore, \( \chi_m = \mu_r - 1 = 5999 - 1 = 5998 \).
