WebFerromagnets with high retentivity and coercivity are used as permanent magnets (hard magnets), while the ones with low retentivity & coercivity (soft magnets) are used as cores in electromagnets. But all ferromagnets have high permeability. WebConclusions. We have established the disproportionation of the Dy 2 Fe 14 B compound in hydrogen at a temperature close to 960 K and under an initial hydrogen pressure of 5.2 MPa into dysprosium hydride, iron, and iron boride. Recombination in a vacuum occurs after heating to 980 K in several stages. Download to read the full article text. billy kramer and the dakotas https://omshantipaz.com
