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.
About Amperes per centimetre
The ampere per centimetre (A/cm) equals 100 A/m. Widely used in European and Japanese magnetics datasheets and IEC standards; soft ferrite B-H curves in power electronics applications are frequently plotted with H in A/cm; magnetic core loss characterisation in IEC 60404 uses A/cm for H values. 1 A/cm = 100 A/m = 4π/10 Oe.
