In the example diagram I have provided how can the counter EMF produced by the conductor moving through the magnetic field be determined?
I am assuming the field is uniform and that the velocity and current in the wire is constant. My logic tells me that there is no net flux cut by the conductor as the magnetic flux is constant although I know this not to be true.

Also, in terms of a solenoid coil if the applied current is alternating with time therefore creating a varying magnetic flux is there any counter EMF produced in the solenoid? Again, my textbook resources would suggest there is but I cannot understand why.
