The field is physical – In the area of space where physical forces manifest themselves, which have reliable records and measurements, we can talk about a physical field. To date, within the framework of modern science, four types of them can be distinguished: gravitational (see here); strong interactions (see here) – nuclear; weak interactions (according to this information) and electromagnetic (according to this information) – magnetic and electric. According to quantum theory, the interaction of material objects at a distance is carried out through the exchange of their field quanta, which are common to each of the listed interactions. Each of the physical fields has its own distinctive features, which are described using strict mathematical formulas.
For several decades now, physicists have not stopped trying to create a unified, comprehensive field theory. It is assumed that she will present all these fields as different manifestations of one – “a single physical field.”
To assert the existence of force fields other than those listed above has no scientific or experimental grounds.
A device for creating a gravitational field.
The gravitational field interacts with physical objects, influencing them. Due to this, the forces of gravitational interaction are directly proportional to their masses, and inversely to the magnitude of the distance between them raised to the second power. According to Newton’s law, it is quantitatively described. It has been established that gravitational forces manifest themselves at any distances between objects.
Gravitons are quanta of the gravitational interaction field. At the same time, their rest mass is zero. Gravitons have not yet been discovered, but their existence follows from the most general theoretical assumptions, and this is beyond doubt.
Among all the phenomena of the universe, the gravitational field plays a key role in most processes.
In nuclear interactions, there is a strong interaction.
The strength of the field of strong interactions is manifested in the fact that it affects nucleons, which are elementary particles that make up atomic nuclei. It is able to combine the charges of protons, which have the same electric charges. This means that it can overcome the forces of their repulsion.
The force associated with this field is inversely proportional to the fourth power of the distance between the nucleons, which means that it is effective only at short distances. Due to the fact that the distances between the particles are 10-15 meters, the field of strong interactions becomes ten times more powerful than the electric field.
Gluons are elementary particles that are quanta of the strong interaction field. The lifetime of a gluon is 10-23 seconds.
This fact is also important for macro processes in the universe, since without this field, strong interactions would not allow atoms to exist.
Is this a consequence of insufficient interaction
The weak interaction, which is the interaction of weak currents, can manifest itself in the case of the interaction of elementary particles at a distance of 10-18 meters between them.
Intermediate bosons are elementary particles that are quanta of the weak interaction field. The lifetime of the intermediate boson is 10-25 seconds.
Currently, it is safe to say that the electromagnetic field and the fields of weak interactions can be combined into a single field theory, which means they have a common nature.
The field of weak interactions plays an important role in the processes that lead to the disintegration and birth of elementary particles, without which the universe could not exist in its current form. During the Big Bang period, this field played a big role.
Electric magnetic
When electric charges interact, which have a magnetic field, it manifests itself as the interaction of an electric field and magnetic fields that are at rest. It can be detected at any distance between charged bodies. Photons are quanta of the electromagnetic field. At the same time, their rest mass is zero.
An electric field has a property that allows it to affect objects that have a charge, which is an electric field. The physical properties and nature of electric charges cannot be unambiguously interpreted, but their values are parameters of the measure of interaction of charged formations that possess this property.
The carriers of the minimum values of charges are electrons and protons, which have a negative charge. There are also other particles that have very short time intervals, such as hydrogen and helium atoms. Objects located in physical reality have a positive charge when the number of protons exceeds the number of electrons, or – in the opposite case – a negative charge.
The increased interaction of charged bodies, including elementary particles and their electric charges, is directly proportional to their electrical characteristics and inversely proportional to the distance between them raised to the second power. It is generally believed that it is quantitatively described by Coulomb’s law. Simultaneously charged and differently charged objects repel and attract.
The expression of a field that has magnetic properties and the force of action on other objects, such as plasma bodies, which also have magnetic properties. The properties of these objects are caused by electric currents, which are the ordered movement of electric charge carriers. The interaction measures determine the intensity of the flowing electric currents, measured in units of time through the cross sections of the conductors. Permanent magnets deal with internal ring molecular currents, which create an effect in their magnetic properties. It follows from this that magnetic forces are of an electrical nature. The ratio of magnetic interaction to electric currents in objects such as magnets is directly proportional to their intensity and inversely proportional to the distance between them raised to the second power. According to this law, it is described as Bio-Savard -Laplace.
The electromagnetic field plays an important role in any processes taking place in the universe involving plasma.
