Question:

The precession frequency of the protons in a laboratory NMR spectrometer is 15.35850 MHz. The magnetic dipole moment of the proton is 1.410608 ∙ 10-26 J/T, while its spin angular momentum is 0.5272863∙10-34 J s. Calculate the magnitude of the magnetic field in which the protons are immersed.
