    A straight wire conductor of length of 0.4m is moving with a speed of 7m/s perpendicular to a magnetic field B of intensity\[0.9 Wb/{{m}^{2}}\]. The induced emf across the conductor is:

    A) 2.52V                           

    B) 25.2V   

    C) 5.26V               

    D) 1.26V

    Correct Answer: A

    Solution :

    Emf induced across the conductor \[\operatorname{E}=Bv\,\,\ell \] \[=0.9\times 7\times 0.4\] \[= 2.52V\]
