I want to know the answer to the following question:
The gyromagnetic ratio is the constant proportion between the magentic field and what?
All the background I'm provided with is that "The gyromagnetic ratio γ is the constant of proportionality between the frequency ν of nuclear magnetic resonance (or electron paramagnetic resonance for electrons) and the applied magnetic field B: ν = γB. It is difficult to measure gyromagnetic ratios precisely because of the difficulties in precisely measuring B, but the value for protons in water at 7002298150000000000♠25 °C is known to better than one part per million.". Is that enough to answer the question?
Answer: yes
