= 12.6. Two coaxial solenoids shown in figure below are connected in series. A current i(t) = 1.5 sin(1000t) A, where time is in seconds, flows through the solenoids. The dimensions are a = 1 cm, b 2 cm, and L = 50 cm. The number of turns in both is the same, N = N 1000. Find the approximate induced electric field at points A (surface of the inner solenoid), A2 (halfway between the two solenoids), and A3 (right outside of the outer solenoid). i(t) i(t) 2a 26 . A3 L =
