    A coil of cross-sectional area \[400\text{ }c{{m}^{2}}\]having 30 turns is making 180 rev/min in a magnetic field of 1 T. The peak value of the induced emf is

    A)  0.4 V                                    

    B)  0.6 V

    C)  226 V                                   

    D)  2.26 V

    E)  22.6 V

    Correct Answer: C

    Solution :

                    \[{{e}_{\max }}=NBA\omega \] \[\therefore \]\[{{e}_{\max }}=30\times 1\times \left( \frac{400}{10000} \right)\times \left( 1800\times \frac{2\pi }{10} \right)\] \[{{e}_{\max }}=226\,V\]
