Question

Consider a conducting rod of length 34 cm moving along a pair of rails, and a magnetic field pointing perpendicular to the plane of the rails.

Required:
At what speed (in m/s) must the sliding rod move to produce an emf of 0.75V in a 1.75T field?

    Answer:

    The speed is  v= 1.26 \ m/s

    Explanation:

    From the question we are told that

       The  length of the rod is  l =  34 \ cm  =  0.34 \ m

        The  induced emf is \epsilon  =  0.75\ V

        The  magnetic field is B  =  1.75 \  T

    Generally the speed is mathematically represented as

           v   = \frac{\epsilon }{Bl }

    =>    v   = \frac{ 0.75 }{1.75 *  0.34 }

    =>   v= 1.26 \ m/s
