NMR - Applied Field Strength

[skyisblue]

The charts that display NMR spectra show the applied field strength increasing from left to right on the x-axis.

Is the applied field strength, the magnetic field that is used to spin-flip the nuclei OR is it just the magnetic field that the compound is already in?
