1 Physics 2213 Homework #14 Fall 2008 Read:Chapter 30, intro, sec. 30.1 – 30.2, 30.4 For study:Chap. 30: Q's #1, 2, 3, 5, 7; (not turned in) E's & P's: #30.1, 9, 23, 25, 67 To be prepared for your 2nd recitation class the week of December 1-5:#30.6 [Inductor] #30.19 [LR Circuit] #30.43 [Mutual Inductance] #30.47 [Inductors in Series & Parallel] #30.61 [Solenoid with Internal Resistance] #1. [World's Largest Inductor?] The enormous elementary particle detector at the Large Hadron Collider, known as the Compact Muon Solenoid (CMS), boasts the world's largest electromagnet: a solenoid 6.0 m in diameter, 12.5 m in length, carrying 20000 A of electric current, and producing a magnetic field of 4.0 T at its middle. (a)Use this information to estimate the number of coils of wire in this solenoid. (You can assume that the infinitely long solenoid approximation applies here.) (b)Estimate the inductanceof this solenoid, approximating the magnetic field inside the solenoid to be uniform along its entire length. (c)How much time(in s and min) would it take to build up the full electric current in the
