A solid cylindrical conductor is supported by insulating disks on the axis of a conducting tube with outer radius R_a = 5.75cm and inner radius R_b = 5.05cm . The central conductor and the conducting tube carry equal currents of I = 1.05A 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 = 5.44cm from the axis of the conducting tube?
