Abstract
Soft magnetic materials play an important role in broad applications, such as transformers and electrical motors. There is an interest in bulk soft magnetic materials because of the demand for miniaturization of cores. We have prepared bulk samples in the form of the small cylinders with good soft magnetic properties. The frequency dependence of magnetic properties is studied, and it is attributed mainly to the structure of the initial powder and domain wall damping. The good combination of various shapes and good soft magnetic properties indicates the possibility of future development as a new soft magnetic compacted material.
Highlights
Soft magnetic alloys are used in many areas including The compacts were cured for 60 min. in an electric transformers for electrical energy distribution, power furnace in Argon atmosphere at a temperature of 520°C
The AC hysteresis loops were measured magnetic alloys used in applications
There is a limitation by AC hysteresis graph MATS-2010SA
Summary
Complex of laminated steels and magnetic ribbons in applications permeability spectra were measured with an impedance consisting of their shape limitation. In prepare bulk material is compaction of powder produced this case, each toroidal sample was modelled as an ideal by milling of amorphous or nanocrystalline ribbons [2]. Soft magnetic composites (SMCs) are typically produced and imaginary (μ'') part of the initial complex by powder processing methods, allowing a net-shape permeability were determined from the inductance Ls and production for a wide variety of shapes and sizes [3]. Resistance Rs of the coil on the toroidal sample using the Magnetic powder parts are produced from powder following relations: particles each covered by insulating coatings, which cause a barrier to particle-to-particle eddy current paths under ac μ=′ L=s.
