Does electron beams act like current carrying wires to themselves?

AI Thread Summary
Two electron beams passing by each other do exhibit magnetic interactions similar to those in current-carrying wires. The nature of the force can be viewed as either purely electric or a combination of electric and magnetic, depending on the observer's frame of reference. This behavior is rooted in the relativistic effects of magnetic force. The discussion highlights the parallels between electron beams and conventional current flow in wires. Understanding these interactions is crucial for applications in fields like particle physics and electromagnetism.

I was just wondering, that if we have two electron beams passing by each other, would there be any magnetic interaction between them ? Just like, electrons in current carrying wires.

I asked the similar question earlier but with the change that one of them was a current carrying wire, whereas here both of them are electron beams.

Since, magnetic force is considered as a relativistic effect, I'm curious how it comes to play when we have only electron beams.

yes, same thing

(and whether you call it a purely electric force, or a mix of electric and magnetic, depends on which frame you're using)
 
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...
