In the classical realm to change the velocity of an electron, the presence of a Lorentz force is essential to act upon it. I
argue that the classical picture is not adequate to understand such changes in the behaviour of microscopic particles. When I
explain the response from quantum mechanical point of view, I find that there is no need to hypothesize the additional classical
ideas. I propose to utilize the set of quantum theoretical principles to resolve the puzzles in the superconducting phase as pointed
out by Hirsch [Phys. Lett. A 315(6)(2003) 474-479]
