Electric-field sentence example
That question can only be answered by examining whether or not the particles move in an electric field.
Let any line drawn in an electric field be divided up into small elements of length.
We may describe, through all the points in an electric field which have the same potential, surfaces called equipotential surfaces, and these will be everywhere perpendicular or orthogonal to the lines of electric force.
Let us suppose any other surface described in the electric field so as to cut the closel y compacted tubes.
Perhaps we may illustrate his position by saying that the elements undergo a change analogous to what takes place in iron, when by being brought into an electric field it becomes magnetic. The substance of the elements remain as well as their accidents, but like baptismal water they gain by consecration a hidden virtue benefiting soul and body.Advertisement
The stark effect from the applied electric field permits access to normally forbidden energy levels.
Moreover any alternating magnetic field will induce an electric field in the tissues exposed to it.
These two models can be distinguished by considering the ratio of the magnetic field perturbation to the electric field.
These produce a uniform electric field between the plates of opposite polarity.
If however an electric field is applied it has the effect of depolarizing the membrane and thereby preventing ATP synthesis.Advertisement
It found a significant dose-response relationship between electric field exposure and incidence.
Lemstrom (88), who was a pioneer in this department, found an electric field highly beneficial in some but not in all cases.
By applying a bias voltage across the capacitors, an electric field is set up within the ferroelectric, causing its permitivity to change.
These free-flowing electrons are directed by the electric field in the cell so that they all flow in one direction to form a current.
This test uses an electric field applied across a slab of gel-like material.Advertisement
When in this condition they become sources of electric force, and the space round them in which this force is manifested is called an " electric field " (see Electricity).
If a small conducting body is charged with Q electrostatic units of electricity, and placed in any electric field at a point where the electric force has a value E, it will be subject to a mechanical force equal to QE dynes, tending to move it in the direction of the resultant electric force.
This provides us with a definition of a unit of electric force, for it is the strength of an electric field at that point where a small conductor carrying a unit charge is acted upon by unit mechanical force, assuming the dielectric constant of the surrounding medium to be unity.
In the same manner, if an electrified body carries a positive charge Q electrostatic units and is placed in an electric field at a place where the electric force or electromotive intensity has a value E units, it is urged in the direction of the electric force with a mechanical force equal to QE dynes.
The change in absorption is measured as a modulated electric field is applied to the sample.Advertisement
This method enables identification of wave modes observed in electric field components.
The convection electric field during this interval is measured in the high-latitude ionosphere using the northern hemisphere SuperDARN HF radar network.
