Inclined Levitron experiments

Abstract

An inclined Levitron demonstration serves to illustrate macroscopically the basic non-quantum mechanical principle of nuclear magnetic resonance. By tuning a “rotary driver” to either the precession or the nutation frequency, the levitated top is made to precess or nutate visibly. By reflecting the beam from a laser-pointer off the Levitron, cycloidal pictures of the induced motion are obtained. Steady inclination at a steep angle is demonstrated in contrast to rotating inclination. Levitron traps are analogous to particle traps. Inclined or horizontal axis operation could lead to nearly frictionless bearings.
