A) \[7.54\times {{10}^{-3}}T~\]
B) \[10.84\times {{10}^{-3}}\,\,T\]
C) \[4.87\times {{10}^{-3}}\,\,T\]
D) \[2.36\times {{10}^{-2}}\,\,T\]
Correct Answer: A
Solution :
Given, \[I=0.6\,m\] \[r=1\,cm\] \[N=600\] \[i=6A\] \[\Rightarrow \] \[{{B}_{inside}}={{\mu }_{0}}ni\] \[=4\pi \times {{10}^{-7}}\times \frac{600}{0.6}\times 6\] \[=4\pi \times {{10}^{-7}}\times 36\times {{10}^{3}}\] \[=7.54\times {{10}^{-3}}\,T\]
