For the concentric transmission line shown in the figure below; let a = 5 cm , b = 7 cm & c = 10 cm and assume that the conductor length is 1m. A DC current of magnitude I = 10 Amperes flows in the line. Take the conductivity o = 10? Siemens a) Without proof, state the expressions of the magnetic field intensity (H) in all regions. b) Use MATLAB to plot (H) vs the radius of the conductor. c) Calculate power losses in the inner and outer conductors separately using Poynting Theorem and compare the results with the losses calculated using 12 R. d) Using the Quickfield software: Plot the magnetic field showing its direction o Plot the Poynting Vector showing its direction O Plot the current density o Draw an XY plot for (H) along the radius of the conductor o Use (Local Values) tab to find the power losses per unit volume in the inner and outer conductors. Compare the total losses to the values obtained in (c). {Hint: Choose problem type (AC Magnetics) and put f = 0} e) If the current flowing in the line is AC with the same magnitude and with f = 50 Hz. o Plot the magnetic field showing its direction o Plot the total current density o Compare the current density with the current density in case of DC current. Find an explanation for the difference between the two cases. с
