It follows from the considerations in the main elaboration that the nucleus of every atom is formed from neutralized protons, which are elementary gravitational charge carriers. Neutralization of a proton means that in front of every proton, in different distances, an electron is placed (see Figure 1).

The figure above shows an uncurled atomic spiral of argon (curling of the spiral goes from the right to the left). From Figure 1 it is clear that every neutralized proton, being a carrier of an elementary gravitational charge, is at the same time a proton-electron type electric dipole. To be more precise, this is an electric dipole positron-electron loaded with electrically neutral ballast from the side of the positron. Electric dipoles of an atom on the odd (1-3-5) and on the even side (2-4-6) of a nucleus are parallel to each other, while in a particular pair (1-2),(3-4) they are in a line and directed contrariwise.

Every electric atomic dipole has a dipole moment.

? = ? ?

P – electric dipole moment [e  m]

e – elementary charge [e]

r – distance of an electron from proton [m]

From the Coulomb’s law

Figure 1 shows such distances calculated for an atom of argon. This means that on the basis of the above formula we can calculate all electric dipole moments contributing to an atom of argon. They are:

Such values of dipole moments can be calculated for an atom of any element in the periodic table.

If an atom is formed of many different electric dipoles, then it has the total electric dipole moment, which is the resultant of the electric moment values of particular dipoles. Such a total electric dipole moment for the presented above atom of argon will be:

and its value is (- 0.55) 10-10 e  m.

The value of the total electric dipole moment can be calculated for an atom of any element in the periodic table.

The values of total electric dipole moments of different atoms do not exceed several units. A small value of total electric dipole moments is due to their compensation as a result of so called pairing phenomenon. Pairing means that electric dipoles of each pair of protons take up antiparallel positions. This is a classical realization of the aim to minimize potential energy through the physical system. The value of the resultant of the electric moment of an atom depends on the values of several last dipoles. These considerations are perfectly illustrated by Figure 1.

Other than zero, the total electric dipole moment of an atom means that in an electric field, each atom, if possible, will try to take up a position parallel to the lines of the electric field, as presented in Figure 2. To make it more clear, an atom of helium was adopted for the considerations.

The higher the resultant value of the total electric dipole moment of an atom, the more parallel position to the lines of the electric field the atom takes up.

Figure 3 shows a view A of the atom presented in Figure 2.

It shows one of the electrons of the atom against an atomic nucleus. The black spots are the lines of the electric field perpendicular to the plane of the figure.
We now move to discuss a current-carrying conductor of circular cross-section. Such a conductor of circular cross-section is shown in Figure 4.

In this conductor, under the influence of electric field, atoms are trying to take up the position as shown above. Parallel to each other and crosswise to the cross-section of the conductor, the atoms are connecting with each other by the magnetic poles of electrons, thus creating a secondary, multi electron magnetic dipole N-S. Asymmetrical structure of the electrons causes that a dipole formed by these electrons is not straight but it bends in the shape of a crescent. As a result, outside of the conductor, there appears a line of the magnetic field of this dipole. Such a line, formed directly by a physically existing magnetic dipole, is the first-order line, the primary line. In a conductor with current, there is a huge number of such magnetic dipoles. A system of primary magnetic lines of these dipoles is shown in Figure 5.

At the intersection points of these lines, there are the resultants of the force vectors, which form new, closed, circular magnetic lines. The closer to the conductor, the stronger the lines are and the denser they are arranged. They are secondary lines, the second order lines, which were nor formed directly by magnetic dipoles. It turns out that the circular lines of the magnetic field of a conductor with current, in a solenoid with current, form the lines of the following, third order. They are also closed lines but of more complex shape (see Figure 6).

This way, only on the basis of theoretical considerations resulting from Model 31, it was shown how a magnetic field is formed  around a conductor with current.

Creating a magnetic field a conductor with current has in general a diameter of a few millimeters, while the field lines formed by the magnetic dipoles of this conductor extend up tens of centimeters. The line of the magnetic dipole formed by a conductor with current has a specific structure. It reminds a ripe ear of grain broken in the middle and bent down to earth again (see Figure 7).

Such a shape of the line causes that it has a few opposite, situated close one to another (almost antiparallel) vectors of force. As it turns out, a human is not able to reveal the existence of such lines. All “human” detectors of magnetic field are too awkward to detect a magnetic line constructed in such a specific way. Thus, a human would have never known about forming a magnetic field by a conductor with current (we would have never built an electric motor), had it not been for the fact that the lines intersect each other as shown in Figure 6, and the resultants of the force vectors of these lines form new, secondary lines of the magnetic field in the shape of a circle (see Figure 8).

All the force vectors of these lines are tangent to them and arranged in the same direction so that they can be detected, for example with a magnetic needle. For the first time it was done by Hans Christian Oersted in 1820.

The result of Oersted’s experiment dismayed the physicists. Here appeared the forces which do not work along the lines of propagating fields, but perpendicularly to them (they are non-central and sourceless). How was the problem resolved by physicists? In Galileo’s way. They formulated the relationships mathematically and admitted that non-central and sourceless forces do occur in nature without going into the details of their formation. This means that the lack of knowledge on the existence of the world of quanta and the world of dark energy led physics to a false conclusion that in nature there occur non-central and sourceless forces.

After this theoretical introduction, we can answer the question.

What is electric current?

Electric current is the ordering of atoms in a conductor, which have other than zero, the total electric moment, under the influence of an external electric field. Simultaneously with this process, the above mentioned atoms form secondary magnetic dipoles in the conductor, which results in the formation of a magnetic field in the space around the conductor.

The greater the total electric moment of a particular element, the greater the level of ordering of its atoms in the space under the influence of a particular electric field. The elements whose atoms have a high value of the total electric moment are now called good conductors of electricity.

For example, the total electric moment is

1,15 x10 -10  exm  for gold,

1,5 x 10-10  exm  for silver,

1,44 x 10-10  exm  for copper.

The elements whose atoms have a low value of the total electric moment are now called bad conductors of electricity.

For example, the total electric moment is

-1,42 x 10-10  exm for nickel,

-1,23 x 10-10  exm for palladium,

-0,86 x 10-10  exm  for platinum.

A few years ago, a Polish professor of physics from the USA  said:
“I wonder and I won’t stop wondering why elements adjacent to one another in the periodic table [nickel (28) and copper (29), palladium (46) and silver (47), platinum (78) and gold (79)] are so much different in electrical conductivity”. In each pair of these metals, one is a very good conductor of electricity (copper, silver, and gold), while the other is a very bad conductor of electricity (nickel, palladium, platinum). It looks like the professor can stop wondering. Gold, silver, copper are good conductors of electricity because their values of total atomic electric moments are high. Platinum, palladium, nickel are bad conductors (they are good resistors) because their values of total atomic electric moments are low.

Current intensity in a conductor is the level of ordering of atoms in this conductor. The higher the level of ordering of atoms, the greater current intensity.

The higher the level of ordering of atoms in a conductor (the greater current intensity), he more disturbed the movement of atoms in the crystal lattice of the conductor, the more difficult the outflow of energy quanta produced by electrons of these atoms, which results in an increase in the temperature of the conductor.

The higher the level of ordering of atoms in a conductor with current (the greater current intensity), the stronger the magnetic field around the conductor is formed by electrons of these atoms. A magnetic field around a conductor with current is a secondary phenomenon, a side effect of ordering of atoms in the conductor.

An important conclusion results from the above considerations.

In every atom, each elementary electric dipole (e -> e+) is in a position perpendicular to the corresponding elementary magnetic dipole (N àS). This means that every atom is the source of crossed dipoles, electric and magnetic (see Figure 9). The number of these crossed dipoles is equal to the number of protons composing a particular atom.

Nowadays, a definition of electric current applied in physics reads as follows:

Electric current is an ordered movement of charges in a conductor, which occurs under the influence of electric field.

According to Model 31, a definition of electric current reads as follows:

Electric current is the ordering of atoms in a conductor, which have other than zero, the total electric moment, under the influence of an electric field.

The above means that, according to Model 31, electric current has nothing in common with a movement of charges in a conductor.

Such an approach to the problem allows to explain why electric currents appears “immediately” in the whole conductor regardless of the length of this conductor. The ordering of atoms which have other than zero, the total electric moment is not connected with their progressive motion. In the case of direct current, it only depends on a one-off rotation of atoms from 00 to 1800 (an arrangement along the lines of the electric field). This arrangement is as fast as the electric field is propagating in the conductor. The propagation of the electric field is a subatomic phenomenon occurring at a speed close to the speed of light. Inertia of the electrons whose motion, according to the current definition, is supposed to be the essence of the flow of electric current is not significant here. In the case of alternating current, atomic dipoles change their position by 1800 every time the electric field changes its direction.

Such an approach to the problem also allows to explain why it is possible to charge a capacitor, although it is an evident break in the electric circuit.

In a capacitor before charging (Figure 10a), the charges of the plates (atoms which have other than zero, the total electric moment) are disorderly.

Nothing is flowing while a capacitor is being charged, but on its plates, under the influence of an external electric field, atoms which have other than zero, the total electric moment are being ordered (Figure 10b). As a consequence, between the plates of the capacitor, a potential difference occurs, resulting in the appearance of the electric field lines in the empty space between these plates. After removing the external field, the inner electric field is maintained between the plates of the capacitor because the potential difference between these plates is maintained. This way, the capacitor becomes the source of current.

For the above case, a definition of electric current based on a movement of charges has proven to be absolutely incorrect. To save this view, J. C. Maxwell introduced to physics quite a new being called displacement current. This ad hoc created concept was necessary to maintain the continuity of current in the space where the charge is not carried. Assuming that, while charging a capacitor, the current flows to one plate and flows away from the other, it had to be presumed that it also flows between the plates in order to maintain the continuity of current in the circuit.

Let us now consider what happens in a charged capacitor (Figure 11a) between whose plates a dielectric has been inserted (Figure 11b).

In a charged capacitor, its charges are ordered with a potential difference between them. When a dielectric is inserted between the plates, its disorderly charges (dipoles) enter the electric field zone and they also become ordered. The amount of ordered dipoles in a capacitor with a dielectric is much greater than the amount of such dipoles in a capacitor without a dielectric, which is manifested in the capacity of the capacitor. Ordered dipoles of a dielectric inserted between the plates of a capacitor substitute some of existing there earlier lines of the electric field, which results in a decrease in the potential difference between the plates of the capacitor.
