Induced emf with no change in flux

AI Thread Summary
When a loop moves in a uniform magnetic field perpendicularly, there is no change in magnetic flux, resulting in no induced electromotive force (emf) according to Faraday's law. The discussion raises the question of whether emf could be generated by a "deflection force," which is not a standard term in physics. Participants clarify that the intended term might be the Lorentz force, which relates to the motion of charges in a magnetic field. The conversation highlights the importance of precise terminology in discussing electromagnetic concepts. Understanding these principles is crucial for grasping the fundamentals of induced emf.

If a loop is moved in a uniform magnetic field such that the direction of its motion is perpendicular to the magnetic field, then no change of flux occurs. Then according to faraday, no emf is induced...

But I was thinking that can the emf be produced in it due to the deflection force?

Hi girlzrule786! :smile:

What is the "deflection force"?
I tried to look it up, but the first hit said it was a special power of the Jedi in Star Wars.
Somehow I don't think that is what you meant! :wink:
 
Did you perhaps mean the Lorentz force?

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...
