Here, also, pure observation of the effect of a conductor in an electric field tells us that its action consists in the annihilation of the field. If the gas thus ionised be left to itself, in the absence of any electric field, the ions, yielding to their mutual attraction, must finally meet, combine, and reconstitute a neutral molecule, thus returning to their initial condition. The drive unit would take water into itself, separate the ionized molecules, and expose them to an electric field. The two faces of the cathode seem to emit rays which are deviated in a direction perpendicular to the lines of force by an electric field, and do not seem to be electrified. electric field | American Dictionaryelectric field noun[ C ] physics the area surrounding an object with an electrical charge where positive and negative particles are reacting with each other electric field intensity Electric field intensity is the strength of electrical energy at a given point in the electric field. Examples of electric fieldelectric field The viscosity is maximal when the vector of velocity is orthogonal to the vector of electricfield, and minimal when these vectors are parallel. The electricfield which accompanies the time change in the axial magnetic field also decreases from the outside to the inside. This means that a cross-field electricfield is produced by the dynamo effect of the cross-field particle drift or acceleration due to electrostatic waves. The amplification factor for the longitudinal electricfield is given and analyzed, as well as the transmission and reflection coefficients. The electricfield is disturbed and turbulent, which confine electrons at the tip. This depletion creates a negative electricfield, which decelerates the ions. However, in a void the comparatively higher ionization rate leads to an electricfield that is directed outward from the void center. This dip develops in a region where the ions experience rapid acceleration due to an abrupt increase in the electricfield. Further, we find that some particles in another positron bunch are accelerated by the parallel electricfield. The energetic electrons launched into vacuum made static longitudinal electricfield and the electricfield accelerated protons into vacuum. When the laser pulse propagates in plasmas, its transverse electricfield is converted into the longitudinal field of the plasma wave, which accelerates the particles. In conjunction with a strong longitudinal electricfield component, a natural acceleration channel has been demonstrated to exist for a laser beam in a vacuum. This cage can then be tracked or manipulated further downstream in the analysis using an electricfield. The particles can be moved by an alternating gas or liquid flow, as in chromatography, or by an alternating electricfield, as in electrophoresis. Both the magnetic and the electricfield are localized in a narrow domain elongated in the transverse direction.
