Bohr Magneton - Definitation, Derivation & Explanation

WebNamed after Niels Bohr, the Bohr Magneton expresses the electron magnetic moment caused by its orbital or spin. When a wave center in the electron is not on the node of a standing wave, it causes motion until on the node. Meanwhile, other wave centers are also affected as one wave center moves to the node, causing a continual spin of the ...
