Optimal Color Mapping for Electric Field Visualization?

AI Thread Summary
For visualizing a cross section of an electric field, it's essential to represent all three components effectively, highlighting both negative and positive values. A color transfer function that uses a diverging color scheme is recommended, as it can distinctly show the variations in magnitude and direction of the electric field components. This approach allows physicists to easily interpret the data and understand the field's behavior. Tools like VectorPlot3D in Mathematica can facilitate this visualization process. Effective color mapping is crucial for conveying complex physical information clearly.

Say you have a cross section of an electric field, and you want to make a visualization, not just of the magnitude, but showing each 3 components (negative and positive). What kind of colour transfer function scheme would you think is best in order to show the information that a physicist would be the most interested in, in the most effective way?

BTW, I wasn't sure where to post this, so feel free to move it if it's in the wrong place. Thanks.

Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'

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.
