Boit's experiment on electrostatics

AI Thread Summary
The discussion centers on an experiment attributed to a scientist named Boit, which is presented on a specific web page. There is skepticism about the existence of this scientist, as no other references to Boit or his experiments can be found online. Participants speculate that "Boit" might be a typo for "Biot," a more recognized figure in the field of electrostatics. The inquiry seeks clarification on Boit's identity and the date of the experiment. Overall, the conversation highlights the challenges of verifying obscure scientific references online.

Hello. On the web address http://etc.usf.edu/clipart/35600/35631/boit_35631.htm there is an apparatus allegedly used by a scientist named Boit. However, I can find no reference elsewhere on the web regarding any scientist with such a name, or even to such experiment. Can someone tell me who was Boit and if possible the date of his experiment? Or Boit is probably a typo and the correct name is Biot?

Thank you.

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.
