Measurement technologies for 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...

Prospects for nanoparticle-based permanent magnets

Magnetic nanoparticles smaller than ~15 nm in diameter and with high magnetocrystalline anisotropies K1 ≥ 1 MJ m can be used as building blocks for next-generation permanent magnets. Advances in processing steps are discussed, such as self-assembly, alignment of the easy axes and appropriate nanostructuring that will enable the fabrication of densely packed nanoparticle assemblies with improved...

Nonlinear Numerical Simulation of Permanent Magnets

Rare earth permanent magnet models are commonly used in the design of undulators and wigglers. Normally the operating point of the magnet in the B vs. H diagram corresponds to a linear reversible characteristic. The region of linearity is strongly dependent on the temperature. The operation of part of the magnet blocks in the region of non-linearity is responsible for the so-called irreversible...
