    A coil of \[20\times 20cm\] having 30 turns is making 30rps in a magnetic field of 1 tesla. The peak value of induced emf is approximately:

    A)  \[452\,V\]                          

    B)  \[226\,V\]

    C)  \[113\,V\]                   

    D)  \[339\,V\]

    Correct Answer: B

    Solution :

    As, emf is given by, \[{{e}_{0}}=NAB\omega \]                 \[=30\times 400\times {{10}^{-4}}\times 1\times 30\times 2\pi =226V.\]
