Unformatted text preview: Version 001 HW18 gavrin (25111) 1 This print-out should have 12 questions. Multiple-choice questions may continue on the next column or page find all choices before answering. Long and Skinny 001 (part 1 of 2) 10.0 points Assume that the length of the solenoid is much larger than the solenoids radius and that the core of the solenoid is air. Calculate the inductance of a uniformly wound solenoid having 230 turns if the length of the solenoid is 37 cm and its cross-sectional area is 4 cm 2 . Correct answer: mH. 002 (part 2 of 2) 10.0 points Calculate the self-induced emf in the solenoid described in the first part if the current through it is decreasing at the rate of 49 A / s. Correct answer: mV. Inductance of a Solenoid 003 (part 1 of 2) 10.0 points A solenoid has 104 turns of wire uniformly wrapped around an air-filled core, which has a diameter of 11 mm and a length of 4 . 2 cm....
