Two concentric coils each of radius equal to \[2\pi \] cm are placed at right angles to each other. 3A and 4 A are the currents flowing in each coil respectively. The magnetic induction in \[Wb/{{m}^{2}}\]at the center of the coils will be \[\left( {{\mu }_{0}}=4\pi \times {{10}^{-7}}Wb/Am \right)\]

A)  \[12\times {{10}^{-5~}}~~\]

B)        \[{{10}^{-5}}~\]

C)  \[5\times {{10}^{-5}}~\]

D)  \[7\times {{10}^{-5}}\]
