Magnetic Field Created by Tile Permanent Magnets

Magnetic Field of Permanent Magnets: Measurement, Modelling, Vizualization

MATLAB language is a quite general and high power language. Thanks to its complexity, simplicity and universality it was used anywhere in the complete study of permanent magnet force action. Main use is the control of fully automated apparatus, data acquisition and processing, numerical integration according to the models of permanent magnets, visualization of results, simulation of the dynamic...

Induction heating of cylindrical nonmagnetic ingots by rotation in static magnetic field generated by permanent magnets

Induction heating of cylindrical nonmagnetic billets by their rotation in static magnetic field is modeled. The magnetic field is produced by a system of appropriately arranged permanent magnets. The numerical model is solved by our own full adaptive higher-order finite element method in a monolithic formulation, i.e., both magnetic and temperature fields are solved simultaneously, respecting t...

Permanent magnets and hard magnetic materials

This review deals with the definition and development of hard magnetic materials with special emphasis on more recent developments in this field. After discussing the fundamental properties of all hard magnetic materials, based on the intrinsic and extrinsic properties, some remarks on the history of hard magnetic materials and permanent magnets are given. The important hard ferrites are only b...

Magnetic reversal in Sm2Fe17Ny permanent magnets

Magnetic forces produced by rectangular permanent magnets in static microsystems.

Finite element numerical simulations were carried out in 2D geometries to map the magnetic field and force distribution produced by rectangular permanent magnets as a function of their size and position with respect to a microchannel. A single magnet, two magnets placed in attraction and in repulsion have been considered. The goal of this work is to show where magnetic beads are preferentially ...
