Field lines for masses vs. electrons

AI Thread Summary
Field lines for masses and electrons differ fundamentally due to the nature of gravitational and electromagnetic forces. Gravitational field lines represent the attraction between masses, while electric field lines illustrate the repulsion or attraction between charged particles like electrons. Although both types of field lines can indicate the direction of force, they operate under different principles and strengths. The inability to predict forces accurately using field lines arises from the distinct characteristics of gravitational and electromagnetic interactions. Understanding these differences is crucial for applying field lines effectively in physics.

Is there any difference between the field lines you draw when one mass approached another mass and when two electrons approach one another? If there is no difference, does this mean field lines can't be used to predict the forces both particles feel?

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.
