<strong>Levitron</strong> – Experiment: Wobbling●15 frames are 1 second●●●There is already a oscillationwithout any perturbationthrough the coil caused bythe airflow and the first pushat the lifting.The “trap frequency“ issignificant smaller than thealready existing oscillationfrequency.Superposition of bothfrequencies
<strong>Levitron</strong> – Summary●●●●●Direct connection between weight of the top and theheight of levitationThere is only a small range where stable levitation ispossibleThere is an upper and a lower limit of the rotationrate of the top for stable levitationThe spinning is the dynamical element, it preventsthe top from overturningConnection with traps for microscopic particles
