2. In the following circuit, there exist a constant and uniform magnetic field in the shaded region. A switch-key can periodically switch between 1 and 2 with time period T. When switch key touches the point 1. The magnetic flux through the circuit is given by 0xl2 0 and when key touches the point 2, the flux through the circuit is Bljla +0 x l2 Blhls. Thus the flux through the circuit changes with time. Do you expect any current flow through the resistance? If yes, where does the energy (= lRt) come from?, and if no, what is your opinion about apparent failure of Faraday's law. You can assume that the key is frictionless and effectively no work is being done in switching between 1 and 2.
