Force/Torque frequency proportional to current frequency

AI Thread Summary
The discussion centers on the relationship between AC current frequency and the force generated, as described by the Lorentz force equation. It questions whether the force produced by a 60Hz AC current will consistently match that frequency, especially in cases of non-linear current flow. Concerns are raised about torque plots from Maxwell showing frequencies that are double the input current frequency, which seems unusual. Participants suggest that this discrepancy may indicate rectification occurring in the circuit. Further clarification and visual data from the user's setup are requested to better understand the situation.

Lorentz force equation shows us that current is proportional to the force. Is it safe to assume that the force generated by an AC current at 60Hz will always have the same frequency? In other words, as the current increases and deceases (sinusoidal) the force will follow the same pattern at the same rate.

Would this be true if the current flow had a circular shape or any non-linear shape? The reason I ask is because Maxwell is giving me torque plots of frequencies twice the frequency of the input current. I find this odd.

Sounds like you are getting some rectification. Can you post some screen shots of your circuit/setup and the output from Maxwell? :smile:

I can get some plots, can you explain a little bit more about what you refer to rectification? Papers that talk about this.

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...
