The paper critically analysis both static vertical and horizontal diamagnetic levitation of a tiny permanent magnet placed into a stationary magnetic field generated by a current loop, or a pair of symmetrically placed current loops. The equilibrium and stability issues are quantitatively treated, allowing an accurate predetermination of the floater’s equilibrium point coordinates and its stability area. The interactions between the levitated magnet, generated magnetic field and the diamagnetic pieces are both analytical and numerical evaluated.
