For a better understanding, we shall resume the explanations by new details.
Let us remember the imaginary experiment, where two particles (bodies, atoms) interact at a distance (attraction or rejection forces) and that space actually intermediates properties of actions: force, direction and sense - vector properties
The reasoning shows that space has a vectors' structure - existence vectors.
This interpretation makes us clearly understand that space is a vector structure.
The existence vectors are all identical and if space is polarized, space passes in the hypostasis of electric field or magnetic field.
We also know that the oriented vectors from the structure of a conductor (electric current without electrons), orients around them other vectors (magnetic current without magnetons)
We keep the differentiation of vectors in electric and magnetic, found as orthogonal, natural and inseparable coupling.
Hence, the left hand, right hand, or drill rule.
There results that the structure of space characterized by the existence of such vectorial coupling is electromagnetic structure.
Therefore, the energetic fluid, fluen, described beforehand the electromagnetic structure of space

This finding has fundamental consequences in knowing the nature:
Is telling us what determines the laws of the motion.
It says that where we measure a magnetic field, we actually deal with the electromagnetic polarization of space (electromagnetic force)
Therefore, magnet "property" and that of bodies electrified by friction, to exert forces, is actually centripetal electromagnetic force (curve oriented space)
It says that the huge "magnetic field" of the sun is electromagnetically polarized space and and because it has a spherical orientation, its electromagnetic force is centripetal.
It says that the properties of matter, elasticity, density, toughness etc. are electromagnetic properties, the matter being actually, electromagnetism (oscillators).
It says that the specter of frequencies (wavelengths) is a specter of energy, a specter of centripetal electromagnetic forces, from galaxies to ... "tough force".
The technology: CT, MRI, ECG, say something? But the atomic links?
