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 eld energy density without calculating the Beld? 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 eld in terms of symbols representing knowns and numerically. d) Now calculate the energy density from the magnetic eld itself. Does the answer agree with the part (a) answer?...
