- Two straight wires carrying current are fixed at the locations shown in the figure below. Three field points (labeled A, B, and C) are also indicated in the figure. Sketch a vector diagram of magnetic fields produced at points A, B, and C in the corresponding boxes below. In each case, sketch the individual magnetic field vectors produced by each current, as well as the net magnetic field. Be sure to label your vectors clearly. (If one of the vectors is zero, explicitly say so.) Calculate the net magnetic field at point C. Express your answer in vector form.arrow_forwardConsider two infinitely-long current-carrying wires separated by a distance d; one carries current I into the page and one carries current I out of the page.
