摘要

Preparing a permanent magnet, comprises preparing a first slurry (3) comprising magnetic particles (4) with a first dimension (13) and at least one organic component, applying a first film (7) made of the first slurry on a carrier film (2), and passing the carrier film on a blade so that a gap with a gap height less than the first dimension remains between the blade and the carrier film for the mechanical alignment of the magnetic particles. An independent claim is also included for the permanent magnet comprising at least one first film made of first slurry with magnetic particles, at least one second film made of second slurry with dysprosium, in which the films are arranged in a stack, and the second film is arranged on at least an outer side of the permanent magnet.
