Question

1) Two very-long current-carrying wires are perpendicular to the plane of the page, with the currents in the directions shown. The distance between the wires is d. The point marked with an x is a distance d directly above the right wire. a) On the figure on your answer sheet, indicate the directions at x of the two fields By and BR due to the two wires. Be sure to label your fields. b) On the figure on your answer sheet, indicate the direction of the total magnetic field at x when IR. Be sure to label this as the total field. I d c) If the total magnetic field at the point x is just in the ty-direction, Brotx 0, what is the ratio of the (The currents are not equal in this case.) Show your work. IR currents
