Magnetic Charge - an overview | ScienceDirect Topics
The theoretical investigation on the existence of magnetic monopoles was initiated by P.A.M. Dirac in [98], where the author analyzed the quantum dynamics of an electron (with electric charge − q = − 1.602 ⋅ 10 − 19 C) in the presence of a magnetic monopole of magnetic charge q m. In the mentioned reference it was shown that wave ...

Quantitative study of the defects of ferromagnetic materials using …
2022年12月15日 · Shi et al [10] considered the influence of the volume magnetic charge, and based on the magneto-mechanical effect, they analyzed and calculated the magnetic charge density distribution, and proposed a three-dimensional magnetic charge model. Compared with the traditional flux leakage method, that model further considers the non-uniform and ...

2021年3月19日 · Previously, magnetic charge defect was shown to mediate electrical conduction in a spin ice material via the interaction between electron's spin, s, at the Fermi surface and the transverse local fluctuation in magnetic field B(k) due to the monopole dynamics (Chern et al., 2013; Lopez-Bara and Lopez-Aguilar, 2017). According to the formulation ...

2023年8月1日 · A true magnetic charge is defined as the source of a static Coulomb-like magnetic field. The Lorentz-force equation shows that the trajectory of an electron moving in a Coulomb-like magnetic field lies on an axially symmetric Poincaré cone [3].
Revisiting the Wu–Yang approach to magnetic charge
2024年9月1日 · This disk magnetic field plays a role similar to the Dirac string in the Dirac approach to magnetic charge — it brings an inward magnetic flux of 4 π g which then gives rise to an outward Coulomb magnetic flux of 4 π g. As with the Dirac string approach we show that placing an electric charge near this disk magnetic field gives rise to a ...
