initials 13. (2 points) Two very, very long conducting wires carry currents in opposite directions, parallel to the y-axis. Current /, flows in the negative-y direction; it is located to the left of the y-axis and runs along the line x = -d = -0.100 m. Current /2 flows in the positive- y direction; it is located to the right of the y-axis and runs along the line x = +d = +0.100 m. The magnitudes of the currents are I1 = 12.0 A and 12 = 18.0 A. (The permeability of free space: Mo = 47 x10-7 Tm/ A.) What is the vector magnetic field, B, at the origin due to this system of two currents? (Please express the magnitude of the magnetic field in units of tesla [T] or micro-tesla [MT], and don't forget to include the vector direction.) y '2 X d 1
