density

[AntonioLao]

Among the concepts of linear density, surface density, and volume density, only volume density makes sense. Nevertheless, in both gravitational and electric potential theory, the Laplacian operator Ѳ operating on the potential functions gives absolute values of density greater than zero. However, when it operates on the magnetic vector or scalar potentials, the results are always zero. There is still no logical explanation for these similarity and distinction among potentials of gravity, electricity, and magnetism.

Therefore, it can be suggested that magnetism could not describe closed surfaces enclosing a definite volume of space and time. If this is not possible then how could magnetic field energy exist? It seems energy density could only make sense if expressed as energy intensity per unit volume.

Antonio,this is getting embarrassing,three great thread starters in a row,keep up this outflow of creative ideation.
You said Antonio,and I quote,"There is still no "logical" explaination for these
similarity and distinction among potentials of gravity,electricity,and magnetism."Unquote.I think the operative word here Antonio is "logical",what is needed is to consider the illogical,and then you will find the answer!Likethe
Ying and Yang,there are two sides to expressed reality,one is the logical,and the other is the illogical,you have to "wholeheartedly" embrace both,to fully
understand the "whole" picture of manifested energy,"shaped" and in-formed
by focussed intent?



kind regards michael.

Energy is truly square integrable and not by any other ways. Furthermore, square of energy as manifestation through the mind is only using the first power of itself, E instead of E times E.
