Consider a cable made from two long, thick, hollow, concentric cylinders, as shown. The inner cylinder has an inner radius or = 2.1 cm and an outer radius b = 4.1 cm, and it carries a total current of I1 = 1.9 A coming out of the page/screen. The outer cylinder has an inner radius b : 4.1 cm and an outer radius c = 5 cm, and it carries a total current of I; =1.1A going into the L'mnfcoursesfl 15632fquizzesf7020 I l midterm 2A: SP22 PHYSICS I25l - ElchagnDpticQM (ITUISJ page/screen. For both cylinders the current is uniformly distributed across their cross-sectional area. (a) What is the magnitude of the magnetic field at a distance r =15 cm from the axis of the cylinders? (b) Where in the region b s r s c (within the outer cylinder, including the inner and outer surfaces) is the magnetic field the strongest? What is the magnitude of the magnetic field at this location? (c) What is the magnitude of the magnetic field at a distance r = 6 cm from the axis of the cylinders
