Active magnetic cloaking with a dipole [PDF]
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.

Comparative study on equivalent models calculating magnetic force between permanent magnets [PDF]
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]
Strong magnetic dipole emission is offered by rare earth ions such as trivalent lanthanides, due to selection rule forbidden electric dipole (ED) transitions.

Modelling the magnetic dipole [PDF]
Three different models of a magnetic dipole, viz., a uniformly magnetised sphere, a circular current loop and a pair of fictitious magnetic charges, have been systematically analysed within the formalism based on the vector potential of the magnetic field.

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

Secular dipole-dipole stability of magnetic binaries
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.

Magnetic Helicity and the Geodynamo
We present theoretical and computational results in magnetohydrodynamic turbulence that we feel are essential to understanding the geodynamo. These results are based on a mathematical model that focuses on magnetohydrodynamic (MHD) turbulence, but ...
