Electron Magnetism: Do Electrons Attract?

AI Thread Summary
Electrons do not attract each other like permanent magnets due to the overwhelming repulsion from their electric charge. While there are rare circumstances where magnetic attraction could occur, these are not typical. The magnetic moment of an electron is too small to create a net attraction between them. Instead, the alignment of electrons can affect the energy levels, modulating the strength of their repulsion. Overall, the primary interaction between electrons remains repulsive rather than attractive.

Do electrons attract to each other like permanent magnets?
 
Physics news on Phys.org
Not really. The repulsion from their electric charge overwhelms any magnetic attraction in most circumstances. There may be some very specific circumstances where this comes into play, but for the most part the magnetic field from their own spin has little effect on them.
 
As Drakkith mentioned, the magnetic moment of the electron is small enough that it never leads to a net attraction. However, it can definitely modulate the strength of the repulsion so that pairs of electrons aligned in different ways will have different energies.

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...
