(a) Calculate the self-inductance of a solenoid that is tightly wound with wire of diameter `0.10 cm`, has a cross-sectional area `0.90 cm^2` and is `40 cm` long   (b) If the current through the solenoid decreases uniformly from `10` A to `0 A` in `0.10 s`, what is the emf induced between the ends of the solenoid?
