Short summary
Fluxgate magnetometers provide magnetic field measurements for geophysics and space physics. A low-noise ferromagnetic ring core typically determines the noise performance of the instrument. Much of the basic research into producing low-noise fluxgate sensors was completed in the 1960s for military purposes and was never publicly released. We present a manufacturing approach that can consistently produce fluxgate ring cores with a noise performance comparable to the legacy ring cores used today.
