I got a different answer than the book. Please let me know if I did this the correct way. For part (a) the book gives the answer as 4.5 * 10 ^ -5 H, and 4.5 * 10 ^ -3 V for part (b). I’ve shown my work below.

144 Check Your (o) Calculate the self-inductance of a solenoid that is tightly wound with 10 cm, has a cross-sectional area of 0.90cm ,and is 40 cm long. (b) If the current through Understanding wire of diameter 0. the solenoid decreases uniformly from 10 to 0 A in 0.10 s, what is the emf induced between the ends of the solenoid?
