About Milliampere Square Meter (mA·m²)
One thousandth of an ampere square meter (10⁻³ A·m² = 10⁻³ J/T).
History: Used for small laboratory permanent magnets and geophysical rock magnetism.
Common Uses: Small motor permanent magnets, paleomagnetic rock sample remanent magnetization measurement.
About Ampere Square Meter (A·m²)
The SI coherent derived unit of magnetic dipole moment, defined as the torque experienced by a magnetic dipole per unit magnetic flux density (m = I · A = τ / B). Dimensionally equivalent to joule per tesla (1 A·m² = 1 J/T).
History: Established through Ampère’s equivalence principle showing that an electric current loop is equivalent to an elementary magnetic dipole.
Common Uses: Permanent magnet dipole moment specifications (NdFeB magnet assemblies), satellite magnetic torque rod attitude control.
