Low frequency electric field induced changes in the shape and motility of amoebas.
Perpendicular and parallel elongation of the giant amoeba, Chaos chaos (Chaos carolinensis), have been observed in alternating electric fields over a wide frequency range (from about 1 hertz to about 10 megahertz). The characteristics change as a function of frequency. Simple dielectric forces may be important in the production of these effects.
