About Magnetic Moments
The magnetic moment quantifies the strength of a magnetic dipole. For quantum systems, it is quantized and related to angular momentum through the gyromagnetic ratio.
Key Formulas:
- Current loop: μ = NIA
- Spin: μs = gs√(s(s+1))μB
- Orbital: μL = √(l(l+1))μB
- Bohr magneton: μB = eℏ/(2me) = 9.274×10⁻²⁴ J/T
