Two concentric coils each of radius equal to \[2\pi \text{ }cm\] are placed at right angles to each other. 3 ampere and 4 ampere are the currents flowing in each coil respectively. The magnetic induction in \[Weber/{{m}^{2}}\] at the centre of the coils will be \[({{\mu }_{0}}=4\pi \times {{10}^{-7}}Wb/A.m)\] [AIEEE 2005]

• A.   \[5\times {{10}^{-5}}\]     
• B.   \[7\times {{10}^{-5}}\]
• C.   \[12\times {{10}^{-5}}\]  
• D.   \[{{10}^{-5}}\]
