FIELD: electrical engineering, and namely, magnetic cores used for manufacture of magnetic elements of electric circuits, for instance, transformers, reactors, chokes, energy storages. SUBSTANCE: the offered magnetic core is distinguished by the fact that magnetic alloy has a partially crystallized amorphous structure; the coating is made on the basis of powder compound, and solidified adhesive is placed between the layers of magnetic alloy band. The invention concerns magnetic cores made of a magnetic alloy band, having both a closed shape, for instance, in the form of band annular magnetic cores, and an open shape, for instance, in the form of band annular magnetic cores with one or several cuts or in the form of a core. The method of manufacture of such magnetic cores is offered as well. EFFECT: enhanced magnetic properties within a wide frequency band. |
