38. (a) Since i = i d (Eq. 32-39) then the portion of displacement current enclosed is i d, enc = i π ( R 3 ) 2 πR 2 = i 1 9 =1 . 33 A . (b) We see from Sample Problems 32-3 and 32-4 that the maximum Feld is at r = R and that (in the interior) the Feld is simply proportional to r . Therefore, B B max = 3 . 00 mT 12 .

Unformatted text preview: 0 mT = r R which yields r = R/ 4 as a solution. We now look for a solution in the exterior region, where the Feld is inversely proportional to r (by Eq. 32-41): B B max = 3 . 00 mT 12 . 0 mT = R r which yields r = 4 R as a solution....
