figure is attached below...traditional EMI problem....conducting rod BC is able to slide on two rails...my qn. is ki in such qn. we say EMF induced is B.l.v.. and its due to change in flux caused by increase in surface area of loop.....what i want to say is that don't we shud consider motional emf produced in rod BC..bcz its moving in B...so net emf induced shud be 2B.l.v instead of only B.l.v...plzz help...where m going wrong!!
