Examples from literature

• Every element of volume rendered a conductor therefore furnishes, in an electric field, equal quantities of positive and negative electricity. 
• 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.
