1. For a long solenoid, we discovered in a problem-of-the-day that B = µ,nl, where n is the number of turns of wire per unit length along the solenoid. a. Use this fact and Faraday's Law of induction to calculate the inductance of a solenoid of cross-sectional area A and length I. b. If a solenoid has 10ʻ turns per meter, and is 5 cm in diameter and 50 cm long, and is carrying a current of 10 A which is turned off in a time of 0.001 sec, what is the induced "back voltage" developed?
