Can Harmonics of Larmor Frequency Affect Proton Precession in NMR?

AI Thread Summary
Harmonics of the Larmor frequency are unlikely to affect proton precession in NMR due to the extremely sharp resonance bandwidth. The discussion confirms that the focus is on NMR and its principles. Participants express uncertainty about the topic, indicating a need for further clarification. Overall, the consensus suggests that harmonics do not play a significant role in proton precession. Understanding the limitations of resonance in NMR is crucial for accurate interpretations.

Would a harmonic of the Larmor frequency have any effect on proton precession?

You're talking about NMR? I think not. The resonance bandwidth is extremely sharp.
 
Yes, I was talking about NMR.

That is what I was thinking, however my knowledge in this area is very limited and just needed more input.

Thanks.
 
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...
It may be shown from the equations of electromagnetism, by James Clerk Maxwell in the 1860’s, that the speed of light in the vacuum of free space is related to electric permittivity (ϵ) and magnetic permeability (μ) by the equation: c=1/√( μ ϵ ) . This value is a constant for the vacuum of free space and is independent of the motion of the observer. It was this fact, in part, that led Albert Einstein to Special Relativity.
