Overview
FrançaisABSTRACT
In a number of electro-technical applications, the essential feature is the conversion of the highest possible power in an often reduced volume, whether it is the workings of a watch, a power distribution transformer or a power plant turbine generator. Every designer, when faced with choosing a material solution that best satisfies the electromagnetic application, is faced with a real compromise. The choice involves the understanding of the phenomena affecting soft-magnetic materials. This article presents the requirements of the different families of application with the current soft-magnetic materials solutions, crystalline or not, that can respond to expected needs.
Read this article from a comprehensive knowledge base, updated and supplemented with articles reviewed by scientific committees.

INTRODUCTION
Crystalline soft magnetic materials" are the subject of four dossiers
The previous
The aim of this dossier [D 2 122] is to confront the requirements of one or other major application family with the current soft magnetic material solutions (crystalline or non-crystalline) that can satisfy them. This dossier is thus an exercise in the art of compromise that any "designer" often has to make when choosing a material solution that best satisfies the electromagnetic application under study.
