<strong>Levitron</strong> – Experiment: Wobbling●●Approximation of the minimum of the total potentialto the potential of a harmonic oscillatorTaylor expansion:V z=⋅B zz−M g zV z=V z 0V ' z 0 z−z 0 1 2 V ' ' z 0z−z 0 2 ...⇒V z= 1 2 V ' ' z 0 z−z 0 2 ...
<strong>Levitron</strong> – Experiment: Wobbling●●●Consideration as harmonic oscillator:V z= 1 2 M 2 z−z 0 2 ⇒ = 1 V ' ' z 02 MExample:– Weight of top M = 20.95g– Height of levitation: 5.8cm⇒≈ M g∂ zB z=−172,84 Am 2We get for the “trap frequency“:=0.23Hz
