Question

An iron rod of susceptibility 599 is subjected to a magnetising field of $1200 A m^{-1}$. The permeability of the material of the rod is : ($\mu_0 = 4\pi 	imes 10^{-7} T m A^{-1}$)

Accepted Answer

$\mu_r = 1 + \chi_m = 1 + 599 = 600$. $\mu = \mu_0 \mu_r = 4\pi 	imes 10^{-7} 	imes 600 = 2400\pi 	imes 10^{-7} = 2.4\pi 	imes 10^{-4} T m A^{-1}$
