    A coil of cross-sectional area \[400\,\,c{{m}^{2}}\] having 30 turns is making 1800 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

    Correct Answer: C

    Solution :

    Induced emf \[{{e}_{\max }}=NBA\omega \] \[\therefore \]  \[{{e}_{\max }}=30\times 1\times \left( \frac{400}{10000} \right)\times \left( 1800\times \frac{2\pi }{60} \right)\] \[{{e}_{\max }}=226\,V\]
