Unformatted text preview: 54. (a) Since the field is decreasing, the displacement current (by Eq. 32-38) is downward, which produces (by the right-hand rule) a clockwise sense for the induced magnetic field. (b) See the solution for part (a). ˆ ˆ (c) and (d) We write E = Ez k = (E0 − ξt)k where ξ = 60000(V/m)/s. From Eq. 32-36 (treated in absolute value) dEz id = ε0 A = ε0 A ξ dt which yields id = 2.1 × 10−8 A for all values of t. ...
