A paramagnetic substance of  susceptibility $2\times {10}^{-4}$ is placed in a magnetic intensity of  ${\text{4×10}}^{\text{-4}}{\text{A-m}}^{\text{-1}}$. Then the intensity of magnetization in the unit of ${\text{A-m}}^{\text{-1}}$ is

• A

  $\text{1}\times {\text{10}}^{-8}{\text{A-m}}^{\text{-1}}$

• B

  $2\times {\text{10}}^{-4}{\text{A-m}}^{\text{-1}}$

• C

  $8\times {\text{10}}^{-8}{\text{A-m}}^{\text{-1}}$

• D

  $16\times {\text{10}}^{-8}{\text{A-m}}^{\text{-1}}$
