In the present study, we consider steady motion of a surfactant-coated drop which falls under gravity and is simultaneously acted upon by a vertical DC electric field. To capture the electric field effects on the fluid flow, we adopt the Taylor-Melcher leaky dielectric framework (Taylor Reference Taylor 1966 ; Melcher & Taylor Reference Melcher and Taylor 1969 ).

As the electrons orbit they accelerate and so lose energy by radiation and therefore slow down and their orbit decreases. It must be remembered that the electric force acts along the line of the electric field direction while the magnetic force acts at right angles to the field direction.

A tiny dielectric or metallic bead is drawn through a cavity while electric field measurements are obtained. Inserting a metallic or dielectric bead into a resonant cavity alters its frequency. This frequency shift is proportional to the sum of the squared amplitudes of the electrical and magnetic fields at the bead's position.
