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 Picoampere-turns
The picoampere-turn (pA·t) equals 10⁻¹² A·t. Relevant in ultra-sensitive flux detection with SQUID magnetometers for magnetoencephalography (MEG), where millikelvin-cooled coils respond to pA·t-level signals from neural currents. 1 pA·t = 10⁻¹² A·t.
