In a hydrogen atom, the magnetic moment associated with electron orbital motion in ground state is approximately one Bohr magneton:
Aμ_B = eh / (4πm) ≈ 9.27 × 10⁻²⁴ A m²
Bμ_B = m c²
Cμ_B = eR
Dμ_B = ε₀
Answer & Solution
Correct answer: A. μ_B = eh / (4πm) ≈ 9.27 × 10⁻²⁴ A m²
Bohr magneton μ_B = eh/(4π m_e) = eħ/(2m_e) ≈ 9.27 × 10⁻²⁴ A m². Fundamental unit of magnetic moment, used in describing atomic magnetism.
