The figure shows, in cross section, several conductors that carry currents through the plane of the figure. The currents have the magnitudes I1 = 3.8 A , I2 = 6.0 A, and I3 = 2.2 A, and the directions shown. Four paths, labeled a through d, are shown. PART C: What is the line integral (int B * dl ) for the path c? The integral involves going around the path in the counterwise direction (Note: express your answer using two significant figures). PART D: What is the line integral (int B*dl) for the path d? The integral involves going around the path in the counterclockwise direction (Note: Express your answer in using two significant figures)
