Frequently Asked Questions
What creates magnetic dipole moments?
Current loops (electromagnets), electron orbital motion, electron spin (intrinsic magnetic moment), and nuclear spin. Permanent magnets have aligned atomic dipole moments.
What is the Bohr magneton?
The fundamental unit of magnetic moment for electrons: μ_B = 9.274 × 10⁻²⁴ J/T. An electron's spin magnetic moment is approximately 1 Bohr magneton.
How are magnets characterized?
By their dipole moment (total strength) and magnetization M (moment per unit volume). Remanence is the residual magnetization after removing the external field. Neodymium magnets have the highest remanence of common magnets.
