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 inch
The ampere per inch (A/in) equals 1/0.0254 A/m ≈ 39.370 A/m. Standard unit in US magnetic core and inductor datasheets from manufacturers like Magnetics Inc. and Ferroxcube; B-H curves and core loss specifications for powder cores and ferrites are commonly plotted in Oe (H-axis) or A/in in North American catalogs. 1 A/in = 1/0.0254 A/m ≈ 39.37 A/m.
