Preamble:

In my cosmic and atomic model it is considered that the basic elements of the Cosmos are Space and Universal Movement (with its time coordinate).
The union of these two basic elements results in cosmic energy, which will logically fill all space since it is one of its components, that is, cosmic energy behaves like a fluid that fills all cosmic space.
Cosmic energy, in its concentric direction on each and every one of the points of the cosmos, creates and acts as gravity, with its well-known properties, that is, to attract and tend to create conglomerations of these points of cosmic energy to create the matter.
But of course, the concentration of energy points in the cosmos already creates an excess of energy in those places, which will be lacking in others.
And to compensate and re-balance the distribution and density of energy throughout the cosmos, a force of redistribution of energy is born or created, which we call Magnetic Force (s).
And in this work what we are going to try to study and explain as simply as possible is the action of this Magnetic Force in its different modalities according to the scope and extent where they are applied.

When matter is created, it forms different systems, bodies and particles, in all of which the magnetic force acts, but both to create these systems and particles, and to join, separate, etc., the magnetic action has to be in different ways of action and at different levels.

Once matter is created by accumulation of energy points, this matter tends to unite and form material particles that by their nature (gravity) also have to unite until they form orbital systems (nucleus with orbitals around them) in order to create a system of large volume and with the average energy density that the Cosmos have as a whole.
As we can see, in the Cosmos matter can unite into larger conglomerates of matter, but conserving a redistribution of energy similar to that which the whole of the Cosmos has (cosmic entropy), and for this it has to form systems with a large nucleus and orbital space around him, watched and defined by the orbitals.
Well, this type of internal or electromagnetic force is responsible for defining the positive orbits (and the total volume of the system), attracting the orbitals and keeping them rotating in their orbits.
These orbits are defined by the potential and speed of rotation of the nucleus, and attracts orbitals whose dimensions and magnetic fields are suitable (in dimension) to be used as such orbitals.

(*) .- Special consideration:

Here it would be important to state that an electromagnetic orbit can attract as an orbital any particle of the required dimensions, even if it is not negatively charged (entropic charge).
For instance, --A positive ion could capture a positron as an orbital, even if it has a positive entropic charge.
--Two positrons (or two protons) could rotate as orbitals between them, although due to their (equal) dimensions this union would be terribly unstable.

1A) Weak forces

Within the internal structuring force we can include the known weak forces that emit radiation or particle emissions from atomic nuclei, which can occur when a well-defined fit between the nuclear mass and the orbital volume is not achieved, that is, , that there is too much nuclear mass for the total dimensions of the nucleus. In this case, nuclear mass is emitted in the form of smaller particles.

This magnetic force (of entropy +/-) will be the one that measures and compares the energy contained in the different particle systems (atoms, stars ...) and tries to make us equal in energy density.
If, for example, in two atoms that are well constituted it turns out that one exceeds the average density of contained energy, and the other has a lack of energy, this magnetic force of rebalancing and equalization of energy in the cosmos unites two atoms so that adding their energy the required average energy density is obtained.
This occurs a lot in chemical reactions, in which one atom gives up an electron (decreases its volume) and is left with excess energy density, and the other acquires that electron and is left with a lack of energy (excess volume), then unites the two atoms in a molecule, leaving the energy density at its proper level again.

In the formation of any orbital system, a total equilibrium in the energy density of the system is never achieved, since their orbits are due to the rotation of the nuclei according to their potential and speed of rotation, and this structuring never coincides with the total equilibrium. in energy density.
To do this, the Magnetic Force executes filling actions of the systems and sets of systems (i.e. molecules) (fine adjustment of density), driving material particles (energy) towards the systems that lack energy, and extracting it from the excess ones.
For this reason and force (thermo-magnetic), all materials that are surplus of energy (higher temperature) try to give this energy to those who lack it (or to a lesser extent), who accept it to balance themselves as much as possible in energy density.

As a separate but complementary topic, we must point out here that in addition to the electromagnetic orbits of atoms, in orbital systems there are also gravitational shells consisting of several magnetic orbits each (2n ^ 2 = 2, 8,8,18, 18, 32) and that due to the rotation of these orbital systems they are created by gravitational forces, which are more extensive than magnetic orbits.
These gravitational layers also tend to be completed or saturated, which makes orbital systems (atoms ...) have a great capacity and diversity of couplings between them, which produces such a diversity of molecules and atomic compounds.
