An iron rod of susceptibility 599 is subjected to a magnetizing field of 1200 A m-1. The permeability of the material of the rod is :$\left( {{\mu _0} = 4\pi \times {{10}^{ - 7}}Tm{A^{ - 1}}} \right)$

Question

An iron rod of susceptibility 599 is subjected to a magnetizing field of 1200 A m^-1. The permeability of the material of the rod is :
$\left( {{\mu _0} = 4\pi \times {{10}^{ - 7}}Tm{A^{ - 1}}} \right)$

$8.0 \times {10^{ - 5}}Tm{A^{ - 1}}$

$2.4\pi \times {10^{ - 5}}Tm{A^{ - 1}}$

$2.4\pi \times {10^{ - 7}}Tm{A^{ - 1}}$

$2.4\pi \times {10^{ - 4}}Tm{A^{ - 1}}$
