If desired, this expression can be simplified to read B i r ar ab = F H G I K J µ 0 22 2 π . (d) Outside the coaxial cable, the net current enclosed is zero. So B = 0 for r a . (e) We test these expressions for one case. If a → ∞ and b → ∞ (such that a > b ) then we have the situation described on page 696 of the textbook. (f) Using SI units, the graph of the field is shown below: 93. (a) Eq. 29-20 applies for r < c . Our sign choice is such that i is positive in the smaller cylinder and negative in the larger one.
