A) \[1.5\times {{10}^{2}}\,A/m\]
B) \[1.58\times {{10}^{6}}\,A/m\]
C) \[1.2\times {{10}^{5}}\,A/m\]
D) \[1.3\times {{10}^{6}}\,A/m\]
Correct Answer: B
Solution :
[b] The total magnetic moment per unit volume. \[=\frac{(8.52\times {{10}^{28}})\times (2\times 9.27\times {{10}^{-24}})}{1}\] \[=1.58\times {{10}^{6}}\,A/m\]You need to login to perform this action.
