So lets say I have a wire of length l moving in a uniform magnetic field of constant velocity. Now the induced EMF = Blv Constant velocity implies constant EMF generated per unit time. I even have a graph of EMF vs time in my textbook for such a situation showing a flat horizontal line for the induced EMF. My question is how can this be true ? The wire cuts the same number of magnetic field lines per unit time. Hence, isn't the rate of change of magnetic flux linkage zero ? So what would a graph of EMF vs time look like for the above situation ?
