📌 Standard Benchmark Reference Values
Standard magnetometer CGS-emu to SI conversion (1 emu = 10⁻³ A·m² = 10⁻³ J/T).
Exact RatioAbout 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.
About Electromagnetic Unit (emu) (emu)
The CGS electromagnetic unit of magnetic dipole moment, defined as 1 erg/G = 10⁻³ A·m² (10⁻³ J/T). Still ubiquitously utilized in solid-state physics and magnetometer software.
History: Historically established in the CGS-emu system; retained by vibrating sample magnetometers (VSM) and SQUID magnetometers.
Common Uses: Vibrating sample magnetometer (VSM) measurements, spintronics magnetic thin film moment readings.
