Maxwell's Law

[IliasTyrovolas1]

I have a query:why rotating charges (i.e. the elecrons in a spool,the orbital electrons,the common electrons of two atoms etc) are not producing EM waves? Their variable electric and magnetic field is not propagated farther than the static.

That's because you're trying to use classical electrodynamics in the quantum domain. Physicists realized this problem over a hundred years ago and started making attempts to solve this problem. The result was a new theory called Quantum Mechanics (QM). In this theory one cannot think of electrons as moving. QM is all about measurement and what you don't measure doesn't exist. For example: until you measure the position of an electron it cannot be said to even have a position. If this seems weird to you then you're on the right track since it really should be weird. We don't have experiences on the quantum domain (i.e. the subatomic) so when we start learning about it we're learning about something we've never experienced before never will experience in the future.

 

Since the charges don't have a position it doesn't have a velocity and thus it remains in a static state inside the atom. When the electron is shed out of the atom things change and when its moving with a bunch of others we can then start to detect magnetic fields. However that gets into quantum field theory which is something I'm not familiar with, yet.

i must confess i'm in no way qualified to answer this question, just my own personal thoughts (strongly influenced by the expanding matter hypothesis).

i tend to think that the atom is sort of a self contained system, and thus as a separate but similar set of laws of physics then the extrnal world around it.

though the electons within the electron shell are moving about in a fairly rapid pace and are interacting with the ouside world, they themselves dont produce an EM field becuase you need an excess of electons on the "surface" of the atom or electon shell in order to achieve that.
