We must, however, assume that the charge Q is so small that it does not sensibly disturb the original electric field, and that the dielectric constant of the insulator is unity.
These rays are not all identical and do not behave in the same way under the action of an electric field and a magnetic field.
Before proceeding to apply some of the facts of Electricity to the solar system, let us find out what is meant by an Electric Field.
So that an electric field may be defined as any region or space in which electric energy is manifested by means of the aetherial electric waves, and across which induction may take place.
Now, in a similar manner, when any body is electrified, the electric waves spread out on every side of the electrified body, and the extent to which the waves spread out form what is known as an electric field.
An electric field is to an electrified body, what a thermal or heat field is to a heated body, or a luminous or lighted field is to a luminous body.
They are slightly deflected by a strong magnetic or electric field.
Imagine now a small portion of an electric field moving at a steady speed; it will produce, owing to its motion, a steady magnetic field.
But experiment shows that whenever the magnetic field at any place is changing an electric field is produced during the alteration, and vice-versa.
If now the motion be stopped, the magnetic field will be destroyed, and the change in the magnetic field will produce an electric field so as to delay the change, i.
An exactly similar result is observed when the magnetic field at a point is changing--an electric field is produced which lasts while the magnetic field is changing.
Another method which has been employed by Rutherford and McClelland is based on the action of an electric field in destroying the conductivity of gas streaming through it.
The velocity of ions in an electric field, which is of fundamental importance in conduction, is very closely related to the coefficient of diffusion.
If there is no electric field, a cloud can be produced some time after the shutting off of the source of radiation, showing that time is required for the recombination of the ions.
When an electric field is produced between the plates, the velocity of the ions between the plates is increased in proportion to the strength of the electric field.
Application of Electric Field If the condensation chamber has two parallel plates for the application of anelectric field like that already described, the ions will be carried at once to the electrodes and disappear.
Any portion of non-conducting space disturbed by electricity is called an electric field.
Thus anelectric field can be mapped or plotted out so that its properties can be indicated graphically.
But it does not follow from this that we ought to regard the variation of an electric field produced at some one point as necessarily consisting of a real displacement of the ether round that point.
Every element of volume rendered a conductor therefore furnishes, in an electric field, equal quantities of positive and negative electricity.
The above list will hopefully provide you with a few useful examples demonstrating the appropriate usage of "electric field" in a variety of sentences. We hope that you will now be able to make sentences using this group of words.
