Mutual inductance in a Conductor

AI Thread Summary
Mutual inductance typically occurs between two conductors that are not electrically connected. In the case of a conductor with a steel core and an aluminum outer layer, mutual inductance is unlikely because the two materials are in direct contact. The lack of insulation between the steel and aluminum means they can influence each other electrically, but this does not constitute mutual inductance. Therefore, the configuration described does not meet the standard conditions for mutual inductance. Understanding these principles is crucial for applications involving electromagnetic fields in conductors.

Friends:

Lets say you have a conductor that is made of two components - an inner core of steel and an outer layer of aluminum (ACSR). Is there mutual inductance between the steel and the aluminum? Every example of mutual inductance I have seen requires that an insulated wire be wrapped around some core. In this case, the steel and aluminum are not insulated. Bare aluminum forms a tubular cylinder around the bare steel. They are touching.

I appreciate any ideas! Thanks.

I believe mutual inductance occurs between two conductors that are not electrically connected, so in your case i don't think so.

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...
