Magnetic fields and moving electrons

AI Thread Summary
The discussion centers on the magnetic field patterns generated by moving charges, specifically comparing the circular magnetic field around a current-carrying wire to that of an isolated electron moving in a vacuum. It raises questions about how the collective magnetic fields of individual electrons in a wire interact to create observable patterns. The potential influence of the vibrations of the ion lattice on the overall magnetic field is also considered. A resource link is provided for further exploration of these concepts. Understanding these interactions is crucial for grasping electromagnetic theory.

Hi forum,
I have been thinking about the circular magnetic field pattern around a long straight current carrying wire and wondering about what the field pattern would be around an isolated electron moving straight in a vacuum? Somehow the magnetic field of all the individual electrons moving in a wire interact to produce the pattern recorded? (Suppose even vibrations of the ion lattice also adds to the overall effect?).
Regards,
Glenn.

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...
