Question

A coaxial cable is constructed from a central cylindrical conductor of radius rA = 1.40 cm carrying current IA = 7.90 A in the positive x direction and a concentric conducting cylindrical shell with inner radius rB = 14.0 cm and outer radius rC = 15.0 cm with a current of 32.0 A in the negative x direction (see figure below). What are the magnitude and direction of the magnetic field at the following points?
