Sentences with phrase «negative electric field»

Electrodes are placed above and below the capsule film: when a positive or negative electric field is applied to an individual electrode, the color particles with the corresponding charge move either to the top or the bottom of a capsule, coloring the display in that spot and outlining an image or text.

Once a positive electric field is applied, the white particle moves to the top of the microcapsule becoming visible to the leader by making the ereader screen white at that specific location and once a negative electric field is applied the black particle behaves the same but making the screen appear darker at that location.

When a positive or negative electric field is applied, corresponding particles move to the top of the microcapsule where they become visible to the viewer.

Not exact matches

But adding parallel magnetic and electric fields introduces a chiral preference: The magnetic field aligns the spins of the positive and negative particles in opposite directions, and the electric field starts the oppositely charged particles moving — positive particles move with the electric field, negative ones against it.

Oxides, a ferroelectric material, develop an internal electric field because their ions move, causing positive / negative charges.

Because an EDM would cause an electron — or, more precisely, its spin axis — to rotate when placed in an electric field, simply sticking an electron between positive and negative electrodes should reveal it, in principle.

Zhao and colleagues found that when the cells were in an electric field, the positively - charged polyamines tend to accumulate at the side of the cell near the negative electrode.

If the charge on the rod were negative, the electric field would induce a dipole moment of reversed polarity, and the particle would still be attracted to regions of high electric field.

As an external electric field polarizes the aircraft, one end of the plane becomes more positively charged, while the other end swings towards a more negative charge.

The recent prediction and experimental realization of standard type - I Weyl fermions in semimetals by two groups in Princeton and one group in IOP Beijing showed that the resistivity can actually decrease if the electric field is applied in the same direction as the magnetic field, an effect called negative longitudinal magnetoresistance.

When the chip's electrodes apply an oscillating electric field, the positive and negative charges inside the nanoparticles reorient themselves at a different speed than the charges in the surrounding plasma.

That is, since water molecules are polar, having a positive end and negative end, they begin to rotate rapidly as the alternating electric field passes through.
