Learning Goal: To practice Problem-Solving Strategy 28.2 Ampere's Law. A solid cylindrical conductor is supported by insulating disks on the axis of a conducting tube with outer radius Ra = 7.15 cm and inner radius R₂ = 5.05 cm. (Figure 1) The central conductor and the conducting tube carry equal currents of I = 2.15 A in opposite directions. The currents are distributed uniformly over the cross sections of each conductor. What is the value of the magnetic field at a distance r = 5.41 cm from the axis of the conducting tube? Figure R₂ Ra 1 of 1 Rank from largest to smallest the values of the magnetic field at the following distances from the axis of the conducting cylinder: Ra = 7.15 cm, Rb = 5.05 cm, r = 5.41 cm, and r > Ra.
