About Picoamperes per metre
The picoampere per metre (pA/m) equals 10⁻¹² A/m. Encountered in magnetic anomaly detection (MAD) systems for submarine hunting, where the difference between Earth's background field and a submerged hull is measured with pA/m sensitivity; atomic magnetometers in zero-field NMR spectroscopy operate at this level. 1 pA/m = 10⁻¹² A/m = 10⁻³ nA/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.
