⚠️ Disclaimer
The Magnetic Moment Calculator is intended for educational and informational purposes only. It calculates the spin-only magnetic moment using the simplified formula μ = √n(n + 2), which assumes that only electron spin contributes to magnetism. This model does not account for orbital angular momentum, spin–orbit coupling, or relativistic effects, which may be significant in certain elements and compounds. The results should not be considered a substitute for experimental measurements or advanced theoretical analysis. Users are advised to consult academic references or subject experts for precise scientific evaluation.
