Conductor Field Magnetic Magnetic field Outside

AI Thread Summary

The discussion centers on the misconception that the magnetic field outside a conductor is zero. It clarifies that a current-carrying conductor, like a copper wire, indeed generates a magnetic field around it. The confusion may arise from the distinction between conductors in equilibrium and those with current flowing. Additionally, it highlights that materials like iron, which can act as conductors, also produce magnetic fields. Understanding the behavior of magnetic fields in relation to conductors is essential for accurate interpretations in physics.

nonequilibrium

Where did you read that it is such?

A copper wire with a current going through it is a conductor, but surely generates a magnetic field.

Maybe you mean a conductor in equilibrium, but still... An iron magnet is a conductor.

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...
