What is the force on a magnetic dipole? [PDF]
European Journal of Physics, 2018 This version presents a more compelling argument that the textbook equation for the force on a magnetic dipole is correct, and is needed to preserve overall momentum ...

Magnetic Field Modification of Optical Magnetic Dipoles
Nano Letters, 2015 Acting on optical magnetic dipoles opens novel routes to govern light-matter interaction. We demonstrate magnetic field modification of the magnetic dipolar moment characteristic of resonant nanoholes in thin magnetoplasmonic films. This is experimentally shown through the demonstration of the magneto-optical analogue of Babinet's principle, where ...

Magnetic dipole interactions in crystals
Physical Review B, 2016 The influence of magnetic dipole interactions (MDIs) on the magnetic properties of local-moment spin systems is investigated. The eigenvalues and eigenvectors of the MDI tensor are determined for a wide variety of spin lattices and magnetic wavevectors in the magnetically ordered state with collinear moment alignments.

On the magnetic dipole energy expression of an arbitrary current distribution [PDF]
arXiv, 2012 We show that the magnetic dipole energy term appearing in the expansion of the magnetic potential energy of a localized current distribution has the form $ U= + \bf{m} \cdot \bf{B}$ which is wrong by a sign from the well known $ - \bf{m} \cdot \bf{B}$ expression.

Determination of the Δ++ magnetic dipole moment
Physics Letters B, 2001 We study the elastic and radiative pi+ p scattering within a full dynamical model which incorporates the finite width effects of the Delta++. The scattering amplitudes are invariant under contact transformations of the spin 3/2 field and gauge-invariance is fulfilled for the radiative case.

Interaction between an electric charge and a magnetic dipole of any kind (permanent, para- or dia- magnetic or superconducting) [PDF]
arXiv, 2015 The interaction between point charge and magnetic dipole is usually considered only for the case of a rigid ferromagnetic dipole (constant-current): here the analysis of force, momentum and energy (including the energy provided by the internal current generator) is generalised to any magnetic dipole behaviour: rigid, paramagnetic, diamagnetic or ...

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.

Simulation of colloidal chain movements under a magnetic field [PDF]
, 2005 Short colloidal chains are simulated by the slithering-snake-algorithm on a simple cubic lattice. The dipole character of the colloidal particles leads to a long range dipole-dipole interaction. The solvent is simulated by the nearest neighbor Ising model.

Bound states of a fermion-dyon system
European Physical Journal C: Particles and FieldsThe bound states of fermions in the external field of an Abelian dyon are studied here both analytically and numerically. Their existence is due to the dyon’s electric charge resulting from a polarization of the fermionic vacuum. The configuration of the

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
