As we have learnt,

 

Intensity of magnetising field -

It is the degree or extent to which a magnetic field can magnetise a substance.

-

susceptivity = x 

Magnetic field instensity = B

 

 Intensity of magnetization (I) = B \times x

\Rightarrow I = Bx = (4\times 10^{-4})\times (3\times 10^{-4}) = 12\times 10^{-8}
