Magnetic levitation by rotation described by a new type of Levitron

Applied Physics 2025-10-31 v3

Abstract

Recently, a novel magnetic levitation phenomenon involving two magnetically equivalent neodymium permanent magnets has been reported. In this work, we propose that this system functions as a scaled-up analog of the Levitron. The key distinction is that the ratio m/μfm_/\mu_f becomes a function of the lateral displacement δR\delta_R, and magnetic trapping no longer depends on the rotational speed of the levitating body as in a conventional Levitron. Furthermore, we demonstrate that stable trapping occurs when a specific constraint on the δR\delta_R parameter is satisfied, ensuring that the potential energy reaches a minimum at the equilibrium point.
