About Millioersteds
The millioersted (mOe) equals 1/(4π) A/m ≈ 79.577 mA/m. Used in magnetic recording media characterisation - remanent coercivity of flexible magnetic media (floppy disks, cassette tape) is often cited in mOe in legacy test standards; sensitive fluxgate magnetometers report data in mOe in older geomagnetic survey literature. 1 mOe = 1/(4π) A/m ≈ 0.07958 A/m.
About Gigaamperes per metre
The gigaampere per metre (GA/m) equals 10⁹ A/m. Encountered only in extreme physics - neutron stars (magnetars) have surface fields of 10⁹-10¹¹ T, corresponding to GA/m to TA/m H-fields; plasma pinch experiments in z-pinch fusion drivers transiently achieve GA/m field strengths along the pinch axis. 1 GA/m = 10⁹ A/m.
