A) \[2\times {{10}^{5}}\,\,A/m\]
B) \[3\times {{10}^{5}}\,\,A/m\]
C) \[4\times {{10}^{5}}\,\,A/m\]
D) \[5\times {{10}^{5}}\,\,A/m\]
Correct Answer: D
Solution :
Given, \[l=3\,cm\], \[A=2\,c{{m}^{2}}\], \[M=3\,\,A\,{{m}^{2}}\] Intensity of magnetization \[=\frac{M}{lA}=\frac{3}{3\times {{10}^{-2}}\times 2\times {{10}^{-4}}}\] \[=\frac{1}{2\times {{10}^{-6}}}=0.5\times {{10}^{6}}=5\times {{10}^{5}}\,A\,{{m}^{-1}}\]
