I have a question: Suppose I have a circuit with a resistor connected to a loop. The circuit is in an electric field. The loop has a 3 way switch that can close the loop regularly, or close the loop by connecting to wire that connects to a different part of the loop. My question is that if I switch the switch is an electric current generated through the wire? I tried to draw it. The wires that aren't connected on the left is where the resistor goes. emf = -dBflux / dt dBflux / dt = integral(B . dA) The field is constant, and I think area is changing, but intuition tells me a current shouldn't be generated.
