we know that a conducting rod moving in a perpendicular const magnetic field creates a motial emf=Blv even if the flux is not changing.but in case closed conducting loop if it moves with velocity v creates an induced emf=Blv only if flux is changing. so i want to know is in first case when the isolated conducting rod is moving in magnetic field why there is an induced emf even if the flux is const.but in the second case its not unless the flux is changing
