Unformatted text preview: 33. (a) The point at which we are evaluating the field is inside the solenoid, so Eq. 31-27 applies. The magnitude of the induced electric field is E= 1 dB 1 r = (6.5 × 10−3 T/s)(0.0220 m) = 7.15 × 10−5 V/m . 2 dt 2 (b) Now point at which we are evaluating the field is outside the solenoid and Eq. 31-29 applies. The magnitude of the induced field is E= (0.0600 m)2 1 1 dB R2 = (6.5 × 10−3 T/s) = 1.43 × 10−4 V/m . 2 dt r 2 (0.0820 m) ...
