Physics 213 Homework #10 Spring 2008 Read: Chap. 30 - intro., sections 30.1 thru 30.3; Chap. 31 - intro., rms (p. 1063-4), section 31.6 For practice: Chap. 30: Q's #Q30.1, 3-7, 13; Chap. 31: Q's #Q31.16, 17 (not quizzed) Chap. 30: E's & P's #30.1, 47; Chap. 31: E's & P's #31.37 To be prepared for your 2nd recitation class the week of April 9-11: Q30.2 [Transformer] #30.9 & 30.10 [Inductor] #30.59 [Solar Magnetic Energy] #30.43 [2 Solenoids] Please add: (c) If instead the current in the inner coil were 0.500 A and were changing at a rate of 37.5 A/s, what would be the magnetic flux through the outer coil and the induced emf in the outer coil? [HINT: Use the general result for a pair of coils linked by mutual inductance: M 21 = M 12 . See section 30.1 for details.] 1. [World's Largest Inductor?] The Compact Muon Solenoid (CMS), which we considered in a previous HW assignment, boasts the world's largest electromagnet: a solenoid 6.0 m in diameter, 12.5 m in length, carrying 20000 A of electric current,
