AI Thread Summary
The discussion revolves around finding a suitable closure for a small leather wallet pouch designed to hold a cell phone and credit cards. The user is considering magnet closures but is concerned about potential interference with electronic devices and credit cards. Suggestions include using a Halbach array to create a magnetic closure that minimizes contact with items being placed inside the pouch. Additionally, there are warnings about the potential risks of using certain materials like eelskin, which may demagnetize cards. Overall, the conversation highlights the need for innovative closure solutions that maintain both functionality and design integrity.

I produce a small wallet size pouch that I have had a lot of problems figuring out how to make it close without impeding on the design of the pouch. The opening is a little over 3 inches. Its used to carry a cell phone and maybe some credit cards. A magnet would be perfect but for anything to get in the bag it would have to pass the magnet. Perhaps this is a stupid question but is there are magnet that is available that won't pose a problem for the cell phones and demagnatize credit cards - or even some sort of technology other than a zipper or snap that is available on the market that will fit well on a small leather good?

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...
It may be shown from the equations of electromagnetism, by James Clerk Maxwell in the 1860’s, that the speed of light in the vacuum of free space is related to electric permittivity (ϵ) and magnetic permeability (μ) by the equation: c=1/√( μ ϵ ) . This value is a constant for the vacuum of free space and is independent of the motion of the observer. It was this fact, in part, that led Albert Einstein to Special Relativity.
