The article on magnetism states that the physical cause of an atomic magnetic dipole (or moment) is two kinds of movement of electrons. In Physics, magnetism is one of the Phenomena by which Materials exert attractive or repulsive Forces on other Materials.
This article clarifies (‽) that electrons don’t actually move in their orbitals. When quantum mechanics refer to “electron orbital motion” they are actually referring to the spatial wave function of the electron. Quantum mechanics is the study of mechanical systems whose dimensions are close to the Atomic scale such as Molecules Atoms Electrons
Just as spin doesn’t mean the particle is actually spinning around an axis in the classical sense, orbital motion doesn’t mean the particle is revolving around the nucleus in the sense of the Bohr model. In Quantum mechanics, spin is a fundamental property of atomic nuclei, Hadrons and Elementary particles For particles with non-zero spin The nucleus of an Atom is the very dense region consisting of Nucleons ( Protons and Neutrons, at the center of an atom In Atomic physics, the Bohr model created by Niels Bohr depicts the Atom as a small positively charged nucleus surrounded by Electrons Likewise, the orbital angular momentum is a quantum value inherent in the electron’s orbital energy state, even though nothing is moving in the classical sense. The Azimuthal quantum number (or orbital angular momentum quantum number, second quantum number) symbolized as l (lower-case L is a Quantum number Furthermore, current loops caused by this orbital motion are also linguistic licence on the part of physicists, because there is neither current (movement of a charge) nor looping going on; but, the mathematical description is very much like that of a classic current loop.
