Unformatted text preview: Review Session I. II. III. Super-conductors A. Resistance is zero, B. current will continue until work is done C. magnetic field is 0 inside the superconductor 1. acts as magnet that opposes magnetic field D. power needed is zero once superconductor has initial current E. things that destroy superconductor 1. excessive temperature/heat 2. excessive external field 3. excessive current density IV. R B T T A. Magnetic moment 1. low energy state is when magnetic fields are aligned 2. high energy state is when the magnetic field is anti-parallel 3. particles can be flipped from aligned to not aligned by sending in a photon 4. particles can be flipped from not aligned to aligned by emitting in a photon 5. (magnetic moment) (fundamental constant) 6. Start all nuclear magnetic resonance problems with E ph = E hf = 2B a. resonant frequency is the f that solves this V. E ph = E VI. |> = a|A> + b|B> A. complex exponential e- i Et/ B. Prob{|A>} = |a e- i Et/ | 2 C. Prob{|>} = |<|>|C....
