Given coaxial cable with an inner conductor with radius a and anouter conducrot with radius b, find B for ρ>b when the inner and outer currents are +100[mA] and-90[mA], respectively, and both conductors are centered along thez-axis. Assume that the positive direction for both currents isthe +z-direction.
