The Weiss magneton was experimentally derived in 1911 as a unit of magnetic moment equal to 1.53 × 10 −24 joules per tesla, which is about 20% of the Bohr magneton. In the summer of 1913, the values for the natural units of atomic angular momentum and magnetic moment were obtained by the Danish physicist Niels Bohr as a consequence of his ...

The toroidal ring model, known originally as the Parson magneton or magnetic electron, is a physical model of subatomic particles. It is also known as the plasmoid ring , vortex ring , or helicon ring .
This page lists examples of magnetic moments produced by various sources, grouped by orders of magnitude.The magnetic moment of an object is an intrinsic property and does not change with distance, and thus can be used to measure "how strong" a magnet is.
The first important paper by Ștefan Procopiu is "Determining the Molecular Magnetic Moment by M. Planck’s Quantum Theory". After studying Planck’s quantum theory and Langevin’s magnetism theory, he established the magnetic moment of the electron and determined the physical constant of magnetic moment, named magneton. [6]
This equation is often represented using derivative notation such that =, where dm is the elementary magnetic moment and dV is the volume element. The net magnetic moment of the magnet m therefore is m = ∭ M d V , {\displaystyle \mathbf {m} =\iiint \mathbf {M} \,\mathrm {d} V,} where the triple integral denotes integration over the volume of ...
The magnetic moment would later be explained in quantum theory by the Bohr magneton (), which is used in the Brillouin function. It could be noted that there is a difference in the approaches of Langevin and Bohr, since Langevin assumes a magnetic polarization μ {\displaystyle \mu } as the basis for the derivation, while Bohr start the ...
In units of the Bohr magneton (μ B), it is −1.001 159 652 180 59 (13) μ B, [2] a value that was measured with a relative accuracy of 1.3 × 10 −13. Magnetic moment of an electron [ edit ]
