AI Thread Summary
Electrolysis for hydrogen generation requires careful selection of conductor materials to avoid contamination. Graphite is commonly used, but alternatives like platinum are also recommended for their effectiveness and purity. Other materials discussed include stainless steel and titanium, which can provide good conductivity without compromising hydrogen quality. The importance of avoiding materials that may leach impurities into the hydrogen is emphasized. Overall, platinum stands out as a top choice for its durability and minimal contamination risk.

I'm trying to use electrolysis to generate hydrogen. I was wondering, what would be the best material to use for the conductor (the exposed part in the water, which generates the bubbles). I know graphite can be used, but what else that will not contaminate the hydrogen. Thanks!

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...
