I want to roll a ball on a material to get the latgest static charge in the ball

AI Thread Summary
To generate the largest static charge on a ball, materials with high triboelectric properties should be considered. A glass ball rolling over a Teflon surface is a viable option, as both materials can create significant static electricity through friction. The low friction of Teflon may enhance the efficiency of charge transfer when the ball rolls. It's important to ensure that the ball maintains contact with the surface to maximize charge accumulation. Overall, using a glass ball on a Teflon surface is likely to produce a notable static charge.

But I don't know what is the best material to use for a ball and flat surface. I was thinking glass ball and typhlon tape at one point, but I have no idea.

Can a rolling ball, roll over a surface and get a charge? with the very low friction?

any insight on this, please help.. :smile:

a glass ball rolling (or rubbed) on hard tough teflon? will that really create static electricity?

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...
