Faraday's electromagnetic induction
I return to the phenomenon of induction, because Faraday's induction
has opened the way to use electromagnetic energy on a large scale.
The phenomenon is the interaction between
"the variation of the magnetic field and a conductor, a coil".
A description of the vector interpreted phenomenon reveals the string of EM interactions:
Induction is the circulation of the vector properties of energy on interactions path.
From this point of view, nature, the universe are phenomena of continuous induction.
In Faraday's induction a magnet (macroscopic field) interacts (vectorially),
with the microscopic magnetism of the atoms in the conductor.
The direction of orientation of the macroscopic field orients the microscopic fields of atoms,
in a common magnetic field (CMF), simultaneously with their electric polarities.
CMF produces centripetal electromagnetic force - voltage U!
If the conductor circuit is closed, the CMF induction propagates
from close to close in both directions, forming an "electromagnet".
The electric polarization of the atoms also propagates (electrostatic),
and their magnetic field enters the CMF and continues (dynamically)
the polarization of the next atoms, with the speed of light.
The EM polarization string is: magnetic-electric-magnetic-electric-magnetic- etc.
So, the magnetism around the conductor represents
the magnetism of the atoms cumulated in the CMF.
Also, the electrical polarities oriented by the magnetic field represent the electrical
polarities of the atoms, which "they pass through atoms, like thread through beads".
The image of this "electromagnetic array" shows that the density of the orientation
of the electrical polarities in the conductor is limited exactly by the presence of their atoms.
In the absence of atoms, electrical polarities would become "electroid," "dark matter."
Atoms are connected in the conductor structure by several electrical and magnetic bonds,
the oriented ones having positions in the structure, easy to orient, or already oriented.
Connections that have not been oriented, although ,
keep the conductor structure intact, resisting the centripetal electromagnetic force (U).
It follows that the centripetal EM force is an action of disintegration
of the conductor (liquefying) and even of the atoms (in the electrode)!
The optimal density of electric polarization (the energy), depending on the size
of the atoms is therefore at the light elements in the table of elements.
This reality has been empirically exploited by practitioners,
starting from the elements of Alessandro Volta to Lithium devices, etc.
