Abstract (en)
[origin: WO2022171348A1] The invention relates to a method for producing a raw magnet (4), wherein - a first raw shape (2.1) is produced from a first magnetic starting material (1.1), - a second raw shape (2.2) is produced from a second magnetic starting material (1.2), - an external magnetic field (21) is applied to at least one raw shape (2), selected from a group consisting of the first raw shape (2.1) and the second raw shape (2.2), during and/or after the raw shape (2) is produced, - a third raw shape (3) is produced from the first raw shape (2.1) and the second raw shape (2.2) by means of joining said raw shapes to one another, - the third raw shape (3) is sintered, and the raw magnet (4) is obtained.
