Question 4 (25 marks] A two-wire transmission line in free space consists of two infinitely long copper wires with identical radii of r = 1 mm. One wire located at x = 5 mm carries 1 A of current in the positive z direction, and the other wire located at x = -5 mm carries 1 A of current in the negative z direction. The currents are uniformly distributed in the cross- section of each wire Determine the line integral of the magnetic field intensity along the following closed contours on the xy-plane 1). The line integral is performed in the clockwise direction. (a) [5 marks] Draw the diagram showing the cross-section view (xy-plane) of the transmission line, the direction of the current and contours of integration, (b) [5 marks] State which law you are going to use. (c) [5 marks] Contour 1 of radius 2.5 mm centered at point (Xı, Yı) = (0,0). (a) [5 marks] Contour 2 of radius 7.5 mm centered at point (x2.72) = (0,0). (e) [5 marks] Contour 3 of radius 2.5 mm centered at point (X3. ) = (-5,0).
