Unformatted text preview: 43. (a) We use Eq. 30-26. The inner radius is r = 15.0 cm, so the field there is B= µ0 iN (4π × 10−7 T · m/A)(0.800 A)(500) = = 5.33 × 10−4 T . 2πr 2π(0.150 m) (b) The outer radius is r = 20.0 cm. The field there is B= µ0 iN (4π × 10−7 T · m/A)(0.800 A)(500) = = 4.00 × 10−4 T . 2πr 2π(0.200m) ...
