Nonuniform Field Effects in Poorly Conducting Media

Abstract

A simplified theory of the behavior of suspended polymer particles in a real liquid dielectric is presented. It is becoming well known that nonuniform fields exert an attractive force of interesting magnitude on particles of high dielectric constant suspended in a liquid medium of lower dielectric constant. In a real dielectric there is an appreciable effect due to the very small currents (10−3 amp at kilovolts applied) which even good liquid insulators support.
