In this reply I argue that “the work done on the bound current densities” can not be “attributed differently”, as Favaro, Kinsler and McCall (FKM) suggest in the preceding Comment. There is a unique physically justifiable expression for this quantity, namely, J b · E. This expression follows from the Newtonian laws of motion. Alternative forms can not be obtained by mathematically manipulating the Poynting identity. I also discuss other points raised by FKM in their Comment.
