Is there a washable magnetic fabric in existence?

AI Thread Summary
The discussion centers on the search for a washable magnetic fabric, with the original poster expressing a business interest in such a material. Participants suggest that a lightweight chain mail made of steel or iron could potentially serve this purpose. There is a lack of concrete information on existing washable magnetic fabrics, indicating a gap in the market. The original poster is encouraged to explore materials science resources for further insights. Overall, the conversation highlights the need for innovative solutions in fabric technology.

Hi, I'm not a materials scientist by any means, but I have a business idea that would involve the use of a washable magnetic fabric. Does anyone know of any such material? If not, does anyone know a good place I might look to find such information? I've tried googling, but I haven't found anything of substance (pun haha... you I'm that lame) yet. Thanks!

Welcome to the PF.

It would seem that a very light chain mail made of steel or iron would work...

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...
