Electrostatic Influence Machines

AI Thread Summary
Electrostatic influence machines, such as Nicholson's Doubler, raise questions about the forces acting on rotating disks during operation. Specifically, there is curiosity about potential drag forces and back attraction or repulsion torques that may occur as the handle is turned. Understanding these forces is crucial for evaluating the efficiency and functionality of these machines. The discussion references both a specific example and a general overview of influence machines for further reading. Overall, the inquiry seeks to clarify the mechanical interactions involved in the operation of electrostatic influence machines.

Hi,

I've been doing some reading on electrostatic influence machines like this one here called Nicholson's Doubler:

www.coe.ufrj.br/~acmq/nicholson.html[/URL]

I was wondering if there is any drag force or back attraction/repulsion torques that the rotating disks would experience as the operator rotates the handle.

Thanks,
Jason O

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...

Thread 'Why measure the speed of light in one direction?'

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.
