AI Thread Summary
Electrons do not have net movement in alternating current (AC); they oscillate back and forth due to the changing direction of the current. In direct current (DC), electrons do move, but their speed is much slower than commonly assumed, a phenomenon known as drift velocity. Understanding these concepts is crucial for grasping the behavior of electric currents. The discussion highlights the fundamental differences between AC and DC in terms of electron movement. Overall, the clarification emphasizes the nature of electron behavior in different types of electrical currents.

Hi I would like to ask you guys something a little basic but is itching my mind, the question is : do electrons have net movement when dealing with ac currents? Suposing we have a sine wave for voltage and current. Thanks in advance !
PD:please excuse any grammar mistake.

No, they don't. They just move back and forth. With DC current, they move but WAY slower than you are likely to expect. Google "drift velocity".
 
Ok thanks I will!

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...
