Abstract
Disclosed is a magnet which is composed mainly of magnetic powders expressed by R-T-B (R is Nd or that partially replaced with rare earth elements and T is Fe or that partially replaced with transition metal.) and a chelate resin or a chelate resin in admixture with other synthetic resins. The magnetic has markedly improved resistance to deterioration caused by oxidation and corrosion.
