CODATA physical constant for the electron magnetic dipole moment.
ApproximateAbout Bohr Magneton (μB)
A fundamental atomic physical constant representing the natural unit for the magnetic dipole moment of an electron due to either orbital or spin angular momentum (μB = eħ / (2m_e) ≈ 9.2740100783 × 10⁻²⁴ A·m²).
History: Proposed in 1913 by Romanian physicist Ștefan Procopiu and named after Danish physicist Niels Bohr in 1920.
Common Uses: Atomic physics, molecular paramagnetism, transition metal ion magnetic moments (e.g. Fe³⁺ spin moments in Bohr magnetons).
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.
❓ Frequently Asked Questions
How many Ampere Square Meters are in 1 Bohr Magneton?
There are exactly 9.27401e-24 Ampere Square Meters in 1 Bohr Magneton (1 μB = 9.27401e-24 A·m²).
What is the formula to convert Bohr Magneton to Ampere Square Meter?
The formula is: Ampere Square Meter = Bohr Magneton / 1.078282e+23. Since 1 Ampere Square Meter = 1.078282e+23 Bohr Magnetons, divide the value in Bohr Magnetons by 1.078282e+23.
How do I convert 1 μB to A·m² manually?
To convert 1 μB to A·m²: apply the formula Ampere Square Meter = Bohr Magneton / 1.078282e+23. Substituting gives: 1 / 1.078282e+23 = 9.274e-24 A·m².
