can someone help with this calculation

two semicircle magnets N-S of strength 'B' encircle a solenoid of length 'L' and move with a constant velocity 'V'. what will be the current 'I' that is induced in solenoid. also, what force will the magnet experience because of this current (Lenz's law)

what is the orientation of these semicircle magnets? are the poles at the end so that they attract each other and make a circle? if so, if could very well be that the induction is zero...the magnetic lines of the magnets simply stay inside the body of the magnets and have no need to go out and turn around to go from north to south. Force=0, too.
