Question 5 (1 point) ) Listen The drawing shows two long, thin wires that carry currents in the positive z direction. Both wires are parallel to the z axis. The 50-A wire is in the x-z plane and is 5 m from the z axis. The 40-A wire is in the y-z plane and is 4 m from the z axis. What is the magnitude of the magnetic field at the origin? 50 A 40 A 5 m 4 m O1x 10-6 T O3 x 106 T 6 X 106 T 04 x 106 T
