Is an EM Field in Cosmos Possible According to Faraday and Maxwell?

AI Thread Summary
The discussion explores the possibility of an electromagnetic (EM) field existing in the cosmos, referencing the theories of Michael Faraday and James Clerk Maxwell. It highlights that light can be viewed as an EM field traveling through three-dimensional space, generated by oscillating electric and magnetic fields. The conversation suggests that Faraday's initial proposals about EM fields could extend to cosmic contexts. Maxwell's equations further codify these concepts, providing a mathematical framework for understanding EM fields. The potential for such fields in the cosmos remains a topic of interest and inquiry.

For this situation, we consider light as an electromagnetic field traveling in x,y and z coordinate of space (cosmos) and electromagnetic fields are produced by oscillating electric and magnetic field.
So can't there be such a similar EM field as proposed by Micheal Faraday?

What Faraday proposed is the EM Field - it was codified by Maxwell.

Thanks

Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'

So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
