Charge seperation in a conducting wire

AI Thread Summary
In a conducting wire with a charge separation, the electric field magnitude can be expressed as V/l, where V is the voltage and l is the length of the wire between the points of charge separation. This formula is valid when l represents the distance over which the voltage is measured. The discussion confirms the correctness of this relationship in the context of electric fields in conductors. Additional resources are provided for further clarification on the topic. Understanding this relationship is crucial for analyzing electric fields in conductive materials.

If I have a conducting wire of length l and a charge separation develops between one end of the wire and the other, will the electric field have a magnitude is equal to: V/l
(voltage/length of wire)??

If your "l" is the length of the wire between two points of charge separation , and "V" is the voltage between the two points of charge separation in the wire , then your formula is correct.

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...
