About Femtoampere-turns
The femtoampere-turn (fA·t) equals 10⁻¹⁵ A·t. Used in SQUID-based nanoscale magnetic sensor calibration and spintronics research where single-turn excitation loops carry femtoampere bias currents. 1 fA·t = 10⁻¹⁵ A·t.
About Ampere-turns
The ampere-turn (A·t) is the SI practical unit of magnetomotive force, defined as F = N × I (turns × current). A 100-turn relay coil at 10 mA produces 1 A·t; power transformer cores typically operate at 100-1000 A·t. 1 A·t = 1 A (turn is dimensionless in SI).
