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 Nanoamperes per metre
The nanoampere per metre (nA/m) equals 10⁻⁹ A/m. Geomagnetic surveys for mineral exploration report spatial variations in Earth's field at nA/m resolution; optically pumped caesium and rubidium magnetometers used in archaeological prospection detect nA/m-scale buried structure anomalies. 1 nA/m = 10⁻⁹ A/m = 10⁻³ µA/m.
