This is an intresting read for any begineer intrested in EM theory like me. But my only question is: In the case of a DC circuit such as this, if the Poynting vector is ExB, I understand that the E field arrows point downward but how can the Total B field arrows be visualized? I understand that the right hand rule means the B lines move concentrically around the current carrying wire, but how to visualize the total B field in the circuit so the S=ExB rule holds? For S to be in the direction of the resistor woundnt there have to be a total B field perpendicular to the E field?
