I think a saturable core can be used to measure a static magnetic

JK I was referring to the similarity to a rotating coil gaussmeter. I
JK think what you're describing now is something more akin to the
JK fluxgate magnetometer.

Relativity transforms static fields into dynamic fields by adding a
velocity component to the measurement.

JK I see. Is Omni magazine still in print by any chance?

Omni is not my cup of tea. Much too glossy for me!
What I meant was if the person taking the measurement is in motion
relative to the field, then the field will seem to be dynamic.
