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 Amperes per metre
The ampere per metre (A/m) is the SI coherent unit of magnetic field strength H, expressing the magnetomotive force per unit length. It defines how strongly a field drives magnetic flux through a material. Earth's geomagnetic H field is approximately 40-60 A/m; a typical transformer core operates at 100-1000 A/m. 1 A/m = 1 A m⁻¹.
