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 Milligilberts
The milligilbert (mGb) equals 10⁻³ Gb = 10/(4000π) A·t ≈ 7.958 × 10⁻⁴ A·t. A CGS submultiple rarely seen in modern practice; encountered in early 20th-century electrical engineering literature and vintage relay test records. 1 mGb = 10/(4000π) A·t.
