MECHANICAL EFFECTS OF AC FIELDS ON PARTICLES DISPERSED IN A LIQUID; BIOLOGICAL IMPLICATIONS

Abstract

A study of the mechanical effects of AC fields is greatly simplified when these effects can be directly observed. Therefore the simplest physical system which would conveniently exhibit the desired behaviour, a suspension of micron sized particles in a simple liquid was used. Four distinct mechanical effects were observed: (1) Forces in inhomogeneous fields, (2) AC electrophoresis, (3) orientation of non-spherical particles, and (4) pearl-chain formation. The first three may be observed on single particles in the field, but the fourth is an interaction between two or more particles brought on by their combined exposure to the field.
