Magnetic dust cores for inductances operating above power frequencies are manufactured from very finely divided magnetisable material, each metal particle being insulated from all its neighbours. The metal powder is of such a fine subdivision that it is commercially known as metal dust.

A number of the more commonly known magnetic core access switches are combined in a single analytical model. In addition to yielding as special cases the known access switches on which it is based, this model produces many apparently new switches. Relationships among the various parameters in this model are developed in such a way that the designer may

The Journal of the Acoustical Society of America, 1981
In a metal-insulator alternate type multilayer head core usable for magnetic sound recording and reproducing, metallic component layers are connected to each other via one or more metallic interconnecting layers passing locally through insulating component layers in order to provide high effective permeability with minimized eddy current loss.

Core loss in buried magnet permanent magnet synchronous motors
IEEE Transactions on Energy Conversion, 1989The steady-state core-loss characteristics of buried-magnet synchronous motors operating from a sinusoidal constant frequency voltage supply are investigated. Measured and calculated core loss, with constant shaft load, is shown to increase with decreasing terminal voltage due to an increase in armature reaction-induced stator flux-density time ...

Core−Shell-Structured Magnetic Ternary Nanocubes
Journal of the American Chemical Society, 2010We report a novel core-shell-structured ternary nanocube of MnZn ferrite synthesized by controlling the reaction temperature and composition in the absence of conventionally used reducing agents. The highly monodispersed core-shell structure consists of an Fe(3)O(4) core and an MnZn Ferrite shell.

Magnetically responsive liquid core polyelectrolyte nanocapsules
Journal of Microencapsulation, 2014The aim of this work was to develop the method of preparation of magnetically responsive, loaded nanocapsules based on a liquid core encapsulation by polyelectrolyte (PE) multilayer adsorption. Magnetically responsive drug nanodelivery systems were prepared by the sequential adsorption of PEs (layer-by-layer technique) using biocompatible PEs (poly-l ...

Magnetic Nanoparticles with Core/Shell Structures
Journal of Nanoscience and Nanotechnology, 2008Magnetic nanoparticles with core/shell structures are an important class of functional materials, possessing unique magnetic properties due to their tailored dimensions and compositions. This paper reviews mainly our recent advances in the preparation and characterizations of core/shell structured magnetic materials, focusing in nonmagnetic ...

Review of Scientific Instruments, 1941
The magnets used in the new University of Illinois mass spectrograph are described. Included is a discussion of the advantages and disadvantages of single casting cores as compared to the usual built-up multiple section type of core. Core designs for mass spectrographic purposes and possible limitations as to size are suggested.

Core–Shell Magnetic Nanoclusters
2009Nanoclusters, aggregates of a few tens to millions of atoms or molecules, have been extensively studied over the past decades. Core–shell nanoclusters have received increasing attention because of their tunable physical and chemical properties through controlling chemical composition and relative sizes of core and shell.
