| contents | Levitation in an almost electrostatic field E. N. Miranda Física, Astronomía y Matemáticas Levitation electrostatic equilibrium points It is well known that a charged particle cannot be in stable equilibrium in a purely electrostatic field. The situation is different in a magnetostaticfield; consequently, magnetic levitation is possible while electrostatic levitation is not. In this paper, motivated by an analogy witha mechanical system, we show that the addition of a small oscillating electrical field to an otherwise electrostatic configuration leads to thestabilisation of unstable equilibrium points. Therefore, levitation becomes possible in an almost electrostatic field. 2004 artículo científico 0035-001X https://www.redalyc.org/articulo.oa?id=57063206 en http://www.redalyc.org/revista.oa?id=570 Revista Mexicana de Física application/pdf Sociedad Mexicana de Física A.C.
