Abstract

The invention relates to a method for utilizing permanent magnets (2), in which the permanent magnets (2) removed from an assembly, in particular from an electric motor, are treated. For cleaning, the permanent magnets (2) are subjected to an abrasive (8). This takes place preferably in a container (1) in which the permanent magnets (2) are set into a relative motion with respect to the abrasive (8). In this way, gentle and rapid cleaning of the permanent magnets (2) is achievable. Furthermore, the invention relates to a device for cleaning permanent magnets (2).
