Measuring field strength of permanent magnets, Physics

I want to measure H, not B
The magnets in question are permanent magnets (large Neo or SmCo magnets), not coils

How can I determine the magnetic field intensity or the mmf of the magnets?
The measurement needs to be something I can actually do, not some giant set of Helmholz coils in outer space
