Name: 3. A long conducting wire with diameter 2a is in the center of coaxial conductor with inner diameter 2b and outer diameter 2c. The inner wire carries a current I coming toward you and the outer conductor carries the same current going away from you. What is the magnetic field in the four regions r < a, a < r < b, b < r < c, and c < r? Assume the current is spread out uniformly in the conductors.
