4. ★★ Two coaxial air-filled solenoids, A and B, of equal length (€ = 20.0 cm) and radii R₁ = 2.50 cm and Rg 5.00 cm have N₁ = 100 turns and NB = 400 turns. (a) The current in the inner solenoid increases from 0 A to 15.0 A in 0.0100 s. What is the induced emf in the outer solenoid during that time? (b) After 0.0100 s, the current in the inner solenoid becomes constant. What is the induced emf in the outer solenoid at that time? (c) How will your answer to part (b) change if an iron core is inserted in the solenoids?
