A Measurement of the Gyromagnetic Ratio of the Proton by the Strong Field Method
The gyromagnetic ratio of the proton in water, γp’, is a physical constant whose value is extensively used to measure magnetic fields precisely by observing precession frequencies. By determining the value of γp’ by the weak and strong field methods we can both express in SI its magnetic fields measured in this way and realise the ampere according to its SI definition with an uncertainty of about a part in a million.
