A novel magnetic dipole inversion method based on tensor geometric invariants

AIP Advances, 2020
Currently, when the existing magnetic dipole inversion methods are used, the classification process heavily relies on the localization results, and the localization error can significantly deteriorate the classification results.

ACCRETION ONTO A MAGNETIC DIPOLE: RESULTS OF 2D NUMERICAL SIMULATIONS

Odessa Astronomical Publications, 2017
Different regimes of accretion to a star with a dipole magnetic field were investigated using 2D numerical axisymmetric resistive MHD simulations. Numerical technique was improved over our recently published results (Toropin et al., 1999, referred as T99

Dual-band light absorption enhancement of monolayer graphene from surface plasmon polaritons and magnetic dipole resonances in metamaterials.

Optics Express, 2017
It is well known that the absorption efficiency of a suspended monolayer graphene in the optical wavelength rang is only 2.3%, which limits its optoelectronic applications.

Spacecraft Attitude Stabilization with Piecewise-constant Magnetic Dipole Moment

, 2015
In actual implementations of magnetic control laws for spacecraft attitude stabilization, the time in which Earth magnetic field is measured must be separated from the time in which magnetic dipole moment is generated.

The radiant massive magnetic dipole

Classical and Quantum Gravity
Abstract We present an exact, time-dependent solution for the Einstein field equations that models the coupling between an anisotropic fluid and a magnetic field in an axially symmetric space-time. By carefully selecting the metric components, we achieve a convenient separation of variables that enables us to solve Einstein’s field ...

Improvement of solar cycle prediction: Plateau of solar axial dipole moment

, 2017
Aims. We report the small temporal variation of the axial dipole moment near the solar minimum and its application to the solar cycle prediction by the surface flux transport (SFT) model. Methods. We measure the axial dipole moment using the photospheric

Circular motion and collisions of particles with magnetic dipole moment and electric charge in dipolar magnetosphere around Schwarzschild black holes

European Physical Journal C: Particles and Fields
No-hair theorem indicates that black holes cannot have their own magnetic dipole moment. They can be weakly magnetized in binary systems with a neutron star companion and an accretion disc of charged particles.

Self-organization of topological defects for a triangular-lattice magnetic dots array subject to a perpendicular magnetic field

Condensed Matter Physics, 2014
The regular array of magnetic particles (magnetic dots) of the form of a two-dimensional triangular lattice in the presence of external magnetic field demonstrates complicated magnetic structures.
