The electric intensity E, current density j and specific resistance k

AI Thread Summary
The relationship between electric intensity E, current density j, and specific resistance k is fundamental in understanding electrical circuits. Electric intensity is proportional to current density, while specific resistance inversely affects current flow. This relationship can be expressed through Ohm's law, which connects these variables in a linear manner. The discussion highlights the need for a comprehensive explanation of these concepts, indicating that the original query lacks sufficient detail. Understanding these relationships is crucial for analyzing electrical systems effectively.

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...
