(b) At r = a , the magnetic field strength is µµ 0 22 0 2 2 i ab a i a π π F H G I K J = c h . At rb Br b =− = , 0 . Finally, for b = 0 B i a r r ir a == 0 2 2 0 2 ππ which agrees with Eq. 29-20. (c) The field is zero for r < b and is equal to Eq. 29-17 for r > a , so this along with the result of part (a) provides a determination of B over the full range of values. The graph
