Demystifying magnetic interactions: This paper presents two derivations of the hyperfine interaction in the ground state of hydrogen, using classical electrodynamics to enhance understanding. The magnetic field B→e, due to the magnetization source M→e(r→) of the 1s electron state, is calculated at the site of the proton moment m→p. This provides the magnetic interaction via −m→p·B→e. One derivation uses the Biot–Savart law; the other applies the magnetic version of Coulomb's Law. By demonstrating the equivalence of these approaches within classical electrodynamics, this work simplifies the understanding of hyperfine interaction. This resource offers a more accessible explanation for students and researchers in atomic physics and related fields.
The American Journal of Physics aims to improve the teaching and understanding of physics. By providing simplified derivations of the hyperfine interaction, this article contributes to the journal's goal of making complex concepts more accessible. The paper's focus on clarity and pedagogical value aligns with the journal's mission to enhance physics education.
