Observer is moving &charge is stationary,magnetic field acts

AI Thread Summary
A magnetic field is only perceived by an observer if there is relative motion between the observer and the charge. When the charge is stationary relative to the observer, it does not produce a magnetic field in that observer's reference frame. If the observer moves while the charge remains at rest, the observer experiences a changing magnetic flux. Conversely, if both the observer and charge move at the same velocity, no magnetic field is detected by the observer. Understanding these concepts is essential in the context of electrodynamics and special relativity.

CASE I - Do magnetic field is felt by observer which is moving and charge is stationary?
CASE II- Do magnetic field is felt by observer which is moving with same velocity as that of charge?
Does it has some experimental proofs and explanations...

There needs to be relative motion between observer and charge for a magnetic field from the charge to be observed.

To put it another way, if the charge is at rest with respect to an observer, then in that observer's reference frame the charge does not produce a magnetic field.
 
When charge is at rest and observer is moving, then with respect to observer the flux changes. Please explain me something on Electrodynamics and special theory of relativity...

With respect to observer the observer isn't moving. You are simply asking about a moving charge.

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...
