About Femtoamperes per metre
The femtoampere per metre (fA/m) equals 10⁻¹⁵ A/m. Used in SQUID (superconducting quantum interference device) magnetometer research to characterise noise floors in ultra-sensitive magnetic field measurements; the Earth's geomagnetic DC drift and biomagnetic fields from neurons produce field gradients at the fA/m level in heavily shielded rooms. 1 fA/m = 10⁻¹⁵ A/m.
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.
