Sir, my doubt is still not clear, as your reply is my doubt.As per your reply, if there is change of flux with rod then emf will be generated. but the complete frame ie rod connected across R is moving continuously with speed v in uniform B (consider it in mid of B only while moving, not enter/exit) then rod should produce emf =Blv as per motional emf concept ie current=Blv/R will flow thru ckt/frame in spite of no change in flux.(please tell agreed/not agreed) But as per as per Faraday law there should not be any emf because no change in area as whole frame/ckt is in B only(consider it in mid of B only while moving, not enter/exit)
why both are contradicting, pl explain now.
