Question

    A conducting rod of length 0.2 m is rotated with angular

    velocity 10 rad/s about one end in a uniform magnetic field of 0.5 T perpendicular to the plane of rotation. Calculate the EMF between the midpoint and the free end of the rod.
    A 75 mV Correct Answer Incorrect Answer
    B 50 mV Correct Answer Incorrect Answer
    C 25 mV Correct Answer Incorrect Answer
    D 100 mV Correct Answer Incorrect Answer

    Solution

    The induced EMF between the center and a point at a distance r from the center of the rotating rod is given by:
