Why velocity affects electromagnetic induction?

AI Thread Summary
Electromagnetic induction occurs due to the interaction between a moving electric charge and a magnetic field, making motion essential for the process. Without motion, an electric field can exist, but a magnetic field requires the flow of charges to be dynamic. This movement generates a magnetic field that can induce an electric current in nearby conductors. The relationship between motion and electromagnetic induction is fundamental, as it allows for the transfer of energy and signals. Understanding this principle is crucial for applications in electrical engineering and technology.

I understand that electromagnetic induction is determined because of a moving electric charge in a magnetic field, but why is the motion necessary? Why is it that motion causes electromagnetic induction and it isn't possible without motion?

If its not moving, you can have an electric field, but the magnetic field is related to the flow, and this flow needs to be in motion to produce a magnetic field.

The magnetic field can then induce an electric current elsewhere, and so forth.

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...
