| contents | 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 $m_/μ_f$ becomes a function of the lateral displacement $δ_R$, 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 $δ_R$ parameter is satisfied, ensuring that the potential energy reaches a minimum at the equilibrium point. |
