The two long straight wires A and B carry currents IA = 6.0 A and I; = 8.0 A, + 3 cm respectively, into and out of the page as shown in the figure. (a) [4 points] What is the magnetic field at the origin (magnitude and IF = 8 A direction) due to wire A? - 4 cm I, =6A (b) [4 points] What is the magnetic field at the origin (magnitude and direction) due to wire B? (c) [4 points] What is the magnitude of the net magnetic field at the origin? On the diagram, sketch a vector showing the direction of the net magnetic field at the origin
