A solenoid with 495 turns has a length of 7.50 cm and a cross-sectional area of 3.10 x 10-9 m2. Find the solenoid's inductance and the average emf around the solenoid if the current changes from +3.50 A to -3.50 A in 5.33 x 10-3 s. HINT Apply the expression for the self-inductance of a solenoid and the self-induced emf of an inductor. Click the hint button again to remove this hint. (a) the solenoid's inductance (in H) (b) the average emf around the solenoid (in V)
