Electric field of moving charge

AI Thread Summary
A moving charge generates a magnetic field, which alters the electric field around it. When a charge moves with uniform velocity, it exhibits different electric and magnetic fields compared to a stationary charge. The magnetic field can be conceptualized by considering the moving charge as a current. Lorentz contraction explains the changes in the electric field, where lines perpendicular to the motion become compressed while parallel lines remain unchanged. Overall, the interaction between electric and magnetic fields is influenced by the charge's motion and relative velocity.

When a charge start motion it produce magnetic field.Is this cause any change in electric filed of this charge?and when there is no acceleration in this charge it will have magnetic field?also is this is relative velocity?

A charge with uniform velocity will have a different electric, and magnetic field than a stationary charge. The magnetic field is easy to understand if you view the moving charge as a current. The electric field change can be understood by lorentz contraction of the electric field lines. The lines parallel to motion are unchanged, but the lines perpendicular to motion get squished together.

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...
