In a hydrogen atom, an electron moves in a circular orbit of radius \[5.2\times {{10}^{-11}}\,m\] and produces a magnetic induction of 12.56 T at its nucleus. The current produced by the motion of the electron will be (Given \[{{\mu }_{0}}=4\pi \times {{10}^{-7}}\,Wb/A-m)\] [MP PET 1997]

A)            \[6.53\times {{10}^{-3}}\,ampere\]                               

B)            \[13.25\times {{10}^{-10}}\,ampere\]

C)            \[9.6\times {{10}^{6}}\,ampere\]                                   

D)            \[1.04\times {{10}^{-3}}\,ampere\]
