Q. Two perpendicular, long, straight wires both of which lie in the plane of the paper. The current in each of the wires is I = 4.5 A. In the drawing dH = 0.13 m and dV = 0.48 m. Find magnitudes of the net magnetic fields at points A and B.
The drawing shows one horizontal wire with the current going up and one vertical wire with the current going to the right. Point A is dH to the right and dV above the intersection. Point B is dH to the left and dV below the intersection.
