    Currents Repel
AI Thread Summary
The discussion centers on the principle that like currents attract while unlike currents repel. It is clarified that two parallel wires with current flowing in the same direction will attract each other, whereas those with current flowing in opposite directions will repel. Participants emphasize the need for a clear definition of "like" and "unlike" currents to fully understand the concept. The conversation also highlights the importance of maintaining original questions for further assistance. Overall, the principles of electromagnetic attraction and repulsion are confirmed through examples of parallel wires.

No one can say whether you are right or not. :smile: You will have to explain what you mean by like and unlike currents.
 
Two parallel wires carrying current in the same direction attract each other. Two parallel wires carrying current in opposite directions repel each other.

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...
