Abstract: A method for manufacturing a magnet from recycled magnets comprising the following steps of: providing: a 1st powder comprising grains of a magnetic phase TR2Fe14B, metal-based compounds and a grain boundary phase rich in rare earth, said 1st powder being free of heavy rare earth, a 2nd powder obtained from recycled magnets comprising heavy rare earths, the 2nd powder is subjected to a hydrogenation-disproportionation treatment, the 1st powder is mixed with the 2nd powder obtained at the end of step b), the mixture obtained at the end of step c) is subjected to a compacting step so as to obtain a compacted part, the compacted part obtained at the end of step d) is subjected to a sintering step so as to obtain a magnet.

Abstract: A sintered annular magnet with a radial orientation of a remanent magnetic field, including: a principal annular part made from a ferromagnetic material, that has a first degree of magnetic anisotropy in the radial direction; and an annular reinforcing part fixed to the principal part of the magnet, the reinforcing part being made from same ferromagnetic material as the ferromagnetic material forming the principal part, and that has a second degree of magnetic anisotropy in the radial direction, the first degree being higher than the second degree.
