Figure 8 shows a coaxial cable (two nested cylinders) of length l, inner radius a and outer radiusb. Note that l >> a and l >> b. The inner cylinder is charged to +Q and the outer cylinder ischarged to −Q.The cable carries a current I, which flows clockwise. Use Ampere’s Law to calculate themagnetic field B⃗ at r < a, a < r < b, and r > b.
