Electric field inside a cavity

AI Thread Summary
The electric field inside a cavity of an irregular conducting surface is zero due to the ability of free charges to redistribute themselves until all points on the surface reach the same electric potential. This redistribution occurs because charges move to eliminate any potential differences, resulting in no electric field within the cavity. The charges reside on the surface of the conductor rather than inside the cavity itself. Consequently, the absence of an electric field is a direct result of the conductor's properties and the behavior of electric charges. Understanding this principle is crucial for grasping electrostatics in conductors.

I have read that electric field inside a cavity of irregular conducting surface having any charge is zero.how is this possible?

Is the charge inside the conductor or inside the cavity?

Because it's a conducting surface, the charges are free to move around. Therefore, all points on the surface must be at the same potential; if they weren't, the freely moving charges would move from the high-potential areas to the low potential areas until the difference was neutralized.

Ok, so all the points on the surface are at the same potential. What's the electric field between two points with the same potential?

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...
