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 Oersteds

The oersted (Oe) equals exactly 1000/(4π) A/m ≈ 79.577 A/m, the CGS unit of magnetic field strength named after Hans Christian Ørsted. Still widely used in permanent magnet characterisation (NdFeB, SmCo, AlNiCo), magnetic recording, and older MRI literature. Earth's surface field is ≈ 0.5 Oe; a typical speaker magnet ≈ 5000 Oe. 1 Oe = 1000/(4π) A/m.
