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).

About Nanoampere-turns

The nanoampere-turn (nA·t) equals 10⁻⁹ A·t. Applicable in fluxgate and search-coil magnetometer calibration for geomagnetic survey instruments, and in micro-inductor testing for CMOS RF circuits. 1 nA·t = 10⁻⁹ A·t.
