What is the mechanism by which an electric charge produces an electric field?

If a substance can build an electric field around it (and if it can build an electric field, it must also build a magnetic field), then we say that it has an electric charge. Electric charge is a property of a substance that creates an electromagnetic field around it. Electric charge is not matter, let alone energy, but a property of matter.

However, sometimes we refer to a matter with an electric charge simply as an electric charge. So, it is important to note that in our common language, electric charge has two meanings. But in a strictly physical context, charge refers only to the properties of matter).

According to quantum field theory, an important cornerstone of modern physics, electric and magnetic fields are a large group of virtual photons that come and go in and out. Charged matter (such as electrons, protons) can emit virtual photons of various sizes, and quickly retract some of the virtual photons emitted by itself, while also absorbing virtual photons emitted by other charged matter (according to the uncertainty principle, as long as the product of the energy of the virtual photon and its survival time is not greater than a certain constant, Planck's constant divided by twice the pi, this emission and absorption is a universal process allowed by nature). It is in this constant emission and absorption that repulsion and attraction are manifested.

Repulsion is like the characters in martial arts or monster movies or games who can create fireballs or flashes of light from the palm of their hands and attack others with them. The "flying" condition of the virtual photon when attracting is somewhat similar to the kind of dart called "flying and coming" thrown by the Australian aborigines. The analogy with the macrocosm can only be a little similar, because in essence, the singularity of the microcosm is completely new and has never been experienced in our daily lives.

Because of this, even the great Albert Einstein was haunted by quantum mechanics describing the microscopic bizarre world.

You asked a really, very, very good question. But the more basic the problem, the more difficult it is.

Some of the following are very good, such as virtual photons, but the photons themselves are very difficult to explain, and it is unlikely that people I believe understand QED or quantum field theory.

It's a chicken-and-egg issue. Physics is not why, because all "whys" have a reason, and finally the first push. But the laws of physics, can be used to explain, and more importantly, can be used to **.

It is to take advantage of the existing law** what will happen in the future, and compare it with the supreme judge of the experiment, so that all the causes are temporary.

The orthodox explanation of this problem, leaving aside the quantum field theory, can tell you responsibly: human beings first discovered the electric charge, and then called the difference between the environment around the charge and the absence of the electric charge called the electric field, that is, it is still determined by experiments. As for quantum field theory, there are some divergent difficulties that cannot be solved, so it is not yet the ultimate theory.

Do you know photons? Photons are not charged, so why are electromagnetic waves essentially light and can also travel? The classical model, which can be interpreted as dipole oscillation, figuratively speaking, means that the electric charge causes the shape of the electromagnetic field in space to change, and the light waves are emitted by squeezing back and forth.

But in true quantum theory:

There is no such thing as an electromagnetic field. Electromagnetism is a classic concept. The light field is quantized, initially in the Jaynes-Cummings model, and even the wave function is quadratically quantized.

This is why it is inappropriate to explain quantum field theory virtual photon exchange.

The electric charge is concentrated at both ends of the plate (or space) under the action of the potential difference, so that the space forms an electric field, to be precise, it is the potential difference between the two ends of the plate (or space) that produces the electric field, not the charge. The accumulation of electric charges is simply a manifestation of the electric field. The charge of the hollow spherical shell is concentrated on both sides of the spherical shell, and the internal field strength is zero---.

Charges are elementary particles with a certain range of energy and activity. When such particles reach a certain scale, an electric field is formed.

This is the law of nature, and this is the way the universe was born, and human beings can only discover and accept it, just as mathematics has a series of axioms that cannot be proved, and physics has a series of phenomena that exist naturally.

Let the two sides be points a and b respectively, and the distance between ab is r, which is equal to the positive charge.

Characteristics of the formed electric field: field strength eo=ea-eb=0 at the midpoint o ;

The field strength at any point p on the line of the two points of charge ep=ea-eb=kq ra?-kq/(r-ra)?

On the line of two equally positive charges, from point A to point B, the electric field strength.

The size decreases first and then increases, and the minimum field strength is zero at Ra=r 2 (i.e., at the midpoint O). The direction of the field strength is first to the right and then to the left, that is, except for the midpoint O, the direction of the field strength points to the midpoint O

In the middle of the line of two equal amounts of positive charges, the sagging accompanies the trapped.

above, n is above the o point, m is below the o point from the o point to the n (m) point, the large reed of the electric field strength increases first and then decreases, when = the maximum value of the field strength; The direction of the field strength is pointed from point o to the ruler good n(m).

Summary. The charge is able to produce an electric field because of its electromagnetic properties. It produces an effect called "electricity" and can also transmit information through magnetic fields.

In addition, the electric field can also propagate through magnetic fields. When an object has a positive or negative charge, it creates a phenomenon called a "magnetic field". This magnetic field travels information out in a variety of ways, affecting surrounding objects.

Why is an electric charge capable of producing an electric field, and how does an electric charge produce an electric field? What is the nature of electric fields?

When an object has a positive or negative charge, it creates a phenomenon called a "magnetic field". This magnetic field travels information out in a variety of ways, affecting surrounding objects.

The principle on which an electric charge produces an electric field is that when a charged particle is in an electrostatic field, it is moved by the force of the electric field. Since the charge itself has mass, it is acted upon by the inertial force determined by the mass of the object, which causes it to move in an electric field.

In addition, since the charge itself has an electric charge, it is also subjected to the electric moment exerted by the same or opposite charge, causing it to move in an electric field. Therefore, when a charged particle is in an electrostatic field, it will be acted upon by the force exerted by the mass of the object and the same or opposite charges, so that it will move in the electrostatic field and produce a new, independent, constant, three-dimensional spatially distributed, symmetrical, weakly polarized, and timeless electrostatic field.

An electric field is essentially a force field generated by charged particles, and it can describe the interaction between charged particles. It is an invisible, invisible energy field that can affect the motion of objects and can also propagate electromagnetic waves. Its intensity depends on the number and distribution of charged particles, and its direction is related to the positive and negative nature of the charge.

Summary. An electric field is a special substance that exists in the space around an electric charge and a changing magnetic field. The electric field is different from the usual physical object, it is not composed of molecular atoms, but it exists objectively, and the electric field has objective properties such as force and energy that ordinary matter has.

Why is an electric charge capable of producing an electric field, and how does an electric charge produce an electric field? What is the nature of electric fields?

Good! Please wait a minute, I'm looking up.

The electric field is a special substance that does not exist objectively due to the subjective consciousness of the person. I believe that the charge placed in a certain space will inevitably change the distribution structure of the surrounding matter, and have a fixed effect on the parts that can be affected in the space, which will change the original spatial trend of the nuclear slag, so that the charge placed in the field will obtain a tendency of relative motion or energy change, that is, the electric field will be generated.

A large number of experimental facts show that the interaction between electric charges is propagated by a field (and an old rather than an over-distance action), which is defined as an electric field. The achievements of modern physics have further affirmed that there is an electric field around the charge, and the electric field between the charges is transmitted and interacted with each other through the electric field of the collapsed tent.

There is a special substance around the electric charge, that is to say, a modified electric nuclear destruction field generated by it, and the force exerted on other charges in the electric field is given by this electric field.

The electric field is a special substance in which the electric charge and the space around the changing magnetic field are accompanied by Zheng Licun. The electric field is different from ordinary physical objects, it is not composed of molecular atoms, but it exists objectively, and the electric field has objective properties such as force and energy that ordinary matter has.

Because of the law of conservation of energy, the electric field force does positive work, the positive charge decreases from high potential to low potential to positive work, and the corresponding negative charge decreases from low potential to high potential, and the electric potential energy also decreases, so the electric potential energy is reduced.

Energy is neither created nor disappeared out of thin air, it simply transforms from one form to another, or from one object to another, while the total amount of energy remains the same. The law of conservation of energy is one of the universal fundamental laws of nature.

An electric field is a special substance that exists in the space around an electric charge and a changing magnetic field. The electric field is a substance that is different from ordinary physical objects in that it is not composed of molecular atoms, but it exists objectively. The electric field has objective properties such as force and energy that are usually possessed by matter.

The nature of the force of the electric field is manifested as follows: the electric field has a force acting on the charge placed in it, and this force is called the electric field force. The properties of the energy of the electric field are as follows:

When the charge moves in the electric field, the electric field force does work on the charge (which indicates that the electric field has energy).

Hope it helps!

In physics, the electrostatic interaction between the charges is achieved by an electric field, but the electric field does not need to be in direct contact with the charge to exert a force on it.

An electric field is a physical field that surrounds matter and is generated by electric charges. When a charge is placed in an electric field, it is subjected to the electric field force because the other charges in the field interact with it to produce an electric field.

According to Coulomb's law, the interaction force between the charges is related to the distance between them and the magnitude of the charge. The electric field force can propagate in space, and the charge only needs to exist somewhere in the electric field, without the need for direct contact with other charges.

In other words, the electric field is created by the electric charge in the space around Shoujing, without the need for actual material contact to produce an action. Even if there is a distance, the electric field force is transferred in the electric field and acts on other charges.

Therefore, the electric field force does not require an electric field to be in direct contact with the charge, it can act on the charge through the presence of the field, regardless of whether there is physical contact between them or not.
