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.
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.
