Magnetization of Magnetite Nanoparticles Mediums with Weak Magnetic Dipole–Dipole Interaction
Journal of Nanoscience and Nanotechnology, 2011Magnetization expression of weak interacting (mH/kT = 1-1.5) magnetite nanoparticles mediums was determined. Experimental and calculated magnetization curves, initial magnetic susceptibility of magnetite nanoparticle mediums were compared. It is showed are agree.

American Journal of Physics, 1971
In this paper we derive the expression for force on a magnetic dipole in an elementary way but without using “poles.” The equation F = (μ ·∇)B follows from concepts of electromagnetism already familiar to the first-year student. This is accomplished by working with forces on current elements and grouping terms to attain recognizable vector identities ...

Enhancing Magnetic Dipole Emission by a Nano-Doughnut-Shaped Silicon Disk
, 2017High-index dielectric nanostructures support inherently strong magnetic dipole (MD) resonances at optical frequencies with minimal dissipative absorptions. They are promising candidates for MD radiation enhancement. Previous investigations, however, show

All-dielectric hollow nanodisk for tailoring magnetic dipole emission.
Optics Letters, 2016We propose a silicon hollow nanodisk for enhancing magnetic dipole (MD) emission. The Purcell factor can be more than 300, which is one order of magnitude larger than the silicon nanosphere case.

Dipole‐Dipole Interaction in Fine Particle Magnets
physica status solidi (b), 1990Contrairement a l'approche precedente qui consistait a caracteriser chaque particule par sa coercitivite propre on considere ici des amas inclus dans un environnement. Les spheres de plus proche voisinage sont decrites comme des particules discretes alors que les autres sont considerees par leur champ de ...

Physics of Fluids, 2017
This work describes a numerical model to compute the translational and rotational motion of N spherical magnetic particles settling in a quiescent viscous fluid under creeping flow condition. The motion of the particles may be produced by the action of gravitational forces, Brownian thermal fluctuations, magnetic dipole-dipole interactions, external ...

GEOPHYSICS, 1959
Two nomograms or alignment charts are presented for the solution of the magnetic‐dipole equations for magnetic intensity over a dipping dipole. The two charts are used in conjunction with each other and are as accurate as is needed for field work. One of these charts will be found useful also in other calculations involving [Formula: see text].
