Unformatted text preview: 8. Say you had a big ideal solenoid with an inductance of L = 10 6 H and volume of V vol = 125 m 3 . The current in the solenoid is I = 100 A. a) Calculate the magnetic ²eld energy density without calculating the B²eld? HINT: This is easier than I thought. b) Calculate the number of turns per unit length in symbols representing knowns (i.e., L , V vol , and I ) and numerically. c) Calculate the magnetic ²eld in terms of symbols representing knowns and numerically. d) Now calculate the energy density from the magnetic ²eld itself. Does the answer agree with the part (a) answer?...
