  • question_answer
    A straight line conductor of length 0.4 m is moved with a speed of 7 m/s perpendicular to a magnetic field of intensity \[0.9\text{ }Wb/{{m}^{2}}\]. The induced e.m.f across the conductor is:

    A) 5.04 V                          

    B) 1.26 V

    C) 2.52 V                          

    D) 25.2 V

    Correct Answer: C

    Solution :

    (c) 2.52 V Magnetic field \[B=0.9\] Length = 0.4 m speed = 7 m/s Induced emf = Blv \[=0.9\times 0.4\times 7=2.52\text{ }V\]
