Mates, due to I understand that in current physics is lost in uncertainty, virtuality, fictional creations, etc., which could take many years to understand the apparently complex magnetic behavior of the cosmos, I would like present the deductions of my cosmic model, in a simple and easy to understand way.
As shown in the model, the universe is completely full of cosmic energy, which behaves like a fluid inside a container, that is, it tries to maintain the same density of this fluid or energy in all places in the cosmos, including to particles and systems composed of them (atoms, stars, galaxies, etc.)
Well, this is the cosmic entropy referring to energy, in which in all places in the cosmos there tends to be the same energy density.
And what force does the cosmos use to achieve this equitable distribution of energy? Well, the magnetic forces.
So,
A.- Cosmic entropy is equality of energy in all places of the cosmos.
B.- Magnetic fields are the fields of forces to achieve this entropy.
Now, to review and understand these magnetic fields a little, we must divide them into two types or classes:

1.- Magnetic forces of external action: Fields or magnetic forces executed from the nuclei of matter that have a great untropy since they contain accumulated a large amount of energy in a small volume of space.
2.- Magnetic forces of external action: Fields of force executed by the cosmic environment outside the particles or particle systems, which try to supply the particle systems, and from the outside, the energy necessary for the system to be in total balance of energy, or entropy.

1.- Magnetic forces of external action:

2.- Magnetic forces of external action:

As for the magnetic forces of external action, and executed by the comic medium as a whole, we can point out some of them.
2-1.- Magnetic forces of a thermal nature, which make the environment outside the systems yield or extract energy from these systems to achieve their total entropy balance.
As an example, we can put the chemical reactions in which, and by changing its orbital structure, an atom is left with a lack of energy, thermal magnetism will supply the energy it needs, and contrary to that if the restructured atom has more energy, it will capture it to give it to another who needs it.
2-2.- This same force is the one that impels the systems that are in imbalance of energy, and electric charge, to come together to form sets of system in equilibrium.
As for example occurs with ions, which have an excess or lack of energy or electrical charge.
2.3.- * As a separate topic, we could include in this section of external action, the magnetic alignment N_S, which is produced by mechanical action of rotating magnetic and gravitational fields, which can approach and join if they rotate in the same direction, and they reject and collide with each other if they turn in the opposite direction.
