Electric field lines

A fictional line or arc traced through a portion of an unoccupied room with its tangent in the path of the electric field vector anywhere at a point is called an electric field line. It can be generated by a point charge or multiple charge system.

Introduction:

Did you know that studying Electrical Field Lines could result in a variety of intriguing designs? Users certainly obviously didn’t learn it in maths class, hence why you must master the notion of Electric Field Lines to fully comprehend what that entails. Let us just look more closely at the idea.

Electric field lines:

Michael Faraday was the first to suggest the notion of an electric field in the nineteenth century. Electric field arcs, according to Faraday, can be utilised to define and understand the unseen electric field. Electric field arcs could be used to illustrate the electric field surrounding a network of particles in a simpler method than utilising a sophisticated vector diagram every time.

Electric field intensity is typically dependent on the length of the electric field lines. Furthermore, because the electrical current is inversely proportional to the square of the distance, as we travel away from the charge, the field of force intensity drops. The orientation of the field of force is depicted by the shafts of the applied field that originate from the positive charge and terminate on the negative charge.

Furthermore, the concentration of ions accurately describes the size of an electric field. A powerful electric field is represented by arcs nearer to the charges, whereas a feeble electric field is represented by lines further away from the charge. This is because as we move farther away from the charges, the magnitude of the field of force weakens.

Electric lines of force are a more productive method of spatially depicting the vector character of a field of force. Instead of numerous vector shafts adjoining a single charge, a sequence of a few lines extending across infinity and the original charge may be more helpful. These patterns of lines, also known as electric lines of force, move in the path that a positive test value deposited on the lines would advance.

These lines are associated with a stationary charge, whereas the magnetic lines of force are associated with moving charges.

Important points related to electric lines of force:

Below are some properties of electric field lines:

  • They originate at the positive charge and terminate at the negative charge
  • If only one charge is present, they do not have an ending point, meaning that they terminate at infinity
  • The magnitude of the field of force is strong if the lines of force are near to each other
  • Huge charges have more lines originating or terminating on them
  • They do not intersect or form a closed network
  • In an environment where there is no charge present, electric lines of force are consistent and uniform
  • The intensity of a charge is dependent on the number of field lines starting or ending at that value.

Rules for drawing Electric field lines of force:

The rules for drawing electric field lines should be followed. Creating such designs of electric lines of force follows several norms and regulations, and properties of electric field lines should also be considered. The norms or rules for drawing electric field lines are essentially set in place to ensure that electric field line designs convey the most possible data about the composition of the electric field encircling a charged object.

Extra arcs are commonly used to encircle more electrified things. powerful electric fields are created by items with more charge. The thickness of these lines can be used to express the magnitude of a field of force in the space that surrounds a charged object, simply covering it with more arcs.

The concentration of lines encircling any particular object exposes data on the magnitude of the charge. It provides data about the intensity of the field of force at that spatial location.

Consider an example. At various distances from the main charge, two distinct spherical cross-sections are generated. The illustration depicts areas of space near and far from the originating charge. Throughout the areas of space nearest towards the charges, the electric lines are tighter collectively, while in the areas of space farthest from the charge, these are wider away.
The field of force should be highest at sites nearest to the charge’s interface and lowest at places farthest from the charge’s cover, according to the line intensity standard. The intensity or strength of a field of force is revealed by the line magnitude in an electric field line design.

At the points in which the arcs link to the edges of things, a second principle for creating electric lines of force is to create the lines of force at right angles to the interfaces of the items. There will never be an electrical force element-oriented parallel to the surface.
The field of force, and hence the electric force, has always been vertical to the surface of an object. Any surplus charge resting on the edge of an origin charge could commence advancing if there was ever an element of force parallel to the surface. It would cause an electric current to pass through the item, which is never seen with electrostatic discharge. When a line of force departs an item’s base, it frequently reverses course.

The junction of lines is a draft law for designing electric lines of force. Crossing electric field lines is not a good idea. When sketching electric lines of force for circumstances that involve an arrangement of ions, this is especially crucial (and easy to forget).  You may probably imagine what would happen if electric lines of force were ever permitted to intersect at a specific point.
The orientation (and intensity) of an electric field inside an area of space is revealed by electric lines of force. If somehow the arcs intersect at a specified place, there have to be two separate quantities of the electric field at a certain point, within each unique way. This was never going to happen. Each point, in reality, does have its field of force that has its intensity and orientation.

Electric Field Lines Attraction and Repulsion:

We know that like charges repel and unlike charges attract, the lines of force between two like charges will be repulsive, and between unlike charges would be attractive.

Conclusion:

Here we have covered the basic concepts of the Electric field of force, properties of electric field lines and Rules for drawing electric field lines, Attraction and Repulsion.
