    Device Project
AI Thread Summary
The discussion centers on a science project focused on Peltier junctions, specifically avoiding circuit board applications. Participants emphasize the correct terminology, noting that it is "Peltier," not "Pelter." There is a request for project ideas that incorporate variables related to Peltier devices. Clarification on the project's scope and objectives is sought, indicating a desire for practical experimentation. Overall, the conversation highlights the interest in exploring the Peltier effect in a hands-on manner.

I'm interested in doing a science project involving pelter junctions, not involving circut board kinds of things.

Something like that would be good, with variables

You have posted this a few times so I KNOW it isn't a typo.

Please take note that it is the PELTIER, not PELTER. In Solid State physics, this is a well-known name given to a well-defined effect.

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.
