Assume that +V(S), is a applied voltage from a power supply, and current I is flowing now in the circuit, and I introduced a (negatively)changing magnetic flied covering a small volume of that conductor, and an EMF is induced in such a polarity above. The circuit as a whole is like so:
Where (D) is the diagram above the circuit schematic, is total applied voltage on the load equal to the induced EMF added to the applied voltage +V? $$V_t = V_S + V_E$$
Because the induced EMF is now in series with the applied voltage? I guess, my confusion with this is the magnetic field is covering a small area, would the voltage still be additive? Vs. the magnetic field covering a larger area inducing a larger EMF at the same polarity?
