Experimental complement of Earnshaw´s Theorem : 4 hours passive magnetic levitation via gravitational potential well using ferrita magnets

We report static magnetic levitation of permanent magnets ferrita in side-by-side (SS)repulsive configuration for T ≥ 15,000 s (4 h). System exhibits angularequilibrium at θ_eq = 24.6° ± 0.5° with quality factor Q = 362 ± 20 from70-second ringdown measurements. Free-fall tests indicate gravitationalpotential contributes to confinement. This constitutes first experimentaldemonstration of gravity-assisted meta-stability complement Earnshaw's theoremfor static permanent magnets at room temperature.
