There are distinct effects depending on the way in which the motion is induced
- An important consequence of the existence of electrical charges on surfaces is that particles will be affected by an applied electric field
- These are collectively defined as electrokinetic effects
- Electrophoresis: the movement of a charged particle relative to the liquid it it suspended in under the influence of an applied electric field
- Electroosmosis: the movement of a liquid relative to a stationary charged surface under the influence of an electric field
