Active magnetic cloaking with a dipole [PDF]

open access: yesAIP Advances, 2020
We theoretically propose and experimentally demonstrate an active quasi-static magnetic cloak enabled by a single magnetic dipole. The cloaking effect can be achieved by active cancelation of the background magnetic field using the magnetic dipole ...

An improved composite ship magnetic field model with ellipsoid and magnetic dipole arrays [PDF]

open access: yesScientific Reports
In order to simultaneously maintain the ship magnetic field modeling accuracy, reduce the number of coefficient matrix conditions and the model computational complexity, an improved composite model is designed by introducing the magnetic dipole array ...

Second order optical nonlinearity of graphene due to electric quadrupole and magnetic dipole effects. [PDF]

open access: yesSci Rep, 2017
We present a practical scheme to separate the contributions of the electric quadrupole-like and the magnetic dipole-like effects to the forbidden second order optical nonlinear response of graphene, and give analytic expressions for the second order ...

Magnetic dipole moments of the Tcc+ and ZV++ tetraquark states [PDF]

open access: yesPhysical Review D, 2021
Inspired by the observation of the doubly charmed state $T_{cc}$ and following theoretical studies on its spectroscopic parameters, we investigate its magnetic dipole moment assigning it the quantum numbers $J^P=1^+$ and both the compact diquark ...

Comparative study on equivalent models calculating magnetic force between permanent magnets [PDF]

open access: yesJournal of Intelligent Manufacturing and Special Equipment, 2020
Purpose – An appropriate equivalent model is the key to the effective analysis of the system and structure in which permanent magnet takes part. At present, there are several equivalent models for calculating the interacting magnetic force between ...

Tailoring Magnetic Dipole Emission by Broken-Symmetry TiO2 Metasurfaces [PDF]

open access: yesEPJ Web of Conferences, 2022
Strong magnetic dipole emission is offered by rare earth ions such as trivalent lanthanides, due to selection rule forbidden electric dipole (ED) transitions.

Secular dipole-dipole stability of magnetic binaries

open access: yesAstronomy & Astrophysics, 2023
Context. The presence of strong large-scale stable magnetic fields in a significant portion of early-type stars, white dwarfs, and neutron stars is well established. Despite this, the origins of these fields remain a subject of ongoing investigation, with theories including fossil fields, mergers, and shear-driven dynamos.

Effects of Barnett Magnetic Dipole–Dipole Interaction on Grain Growth and Destruction

open access: yesThe Astrophysical Journal, 2023
Rapidly spinning magnetic grains can acquire large magnetic dipole moments due to the Barnett effect. Here we study the new effect of Barnett magnetic dipole–dipole interaction on grain–grain collisions and grain growth, assuming that grains are spun up ...

Dipole–Dipole Interactions of Charged-Magnetic Grains [PDF]

open access: yesIEEE Transactions on Plasma Science, 2010
The interaction between dust grains is an important process in fields as diverse as planetesimal formation or the plasma processing of silicon wafers into computer chips. This interaction depends in large part on the material properties of the grains, for example whether the grains are conducting, non-conducting, ferrous or non-ferrous.
