Electric Charges: Understand Electric Currents

AI Thread Summary
Understanding electric currents requires a focused approach rather than broad inquiries. Participants suggest that specific questions or topics should be presented for effective discussion. General explanations are often found in textbooks, and forums are better suited for targeted learning. Engaging with precise issues will facilitate clearer answers and deeper comprehension. Therefore, defining specific areas of confusion is essential for meaningful dialogue on electric currents.

I am not able to understand electric currents.
Can anyone explain?

Perhaps if you could specify exactly what is bothering you, ... Otherwise, I will be just repeating what you can read from a textbook

You should not expect to be taught broad subject areas in this forum. It is why such areas are covered in textbooks and in classes. The most effective way to learn from this forum is when you have specific topic and areas. You have to make an effort to narrow down what exactly it is that you don't understand.

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...
