The present invention relates to a method and to a device for inspecting railway wheels with regard to usage-induced wear and/or material defects. The aim of the invention is to provide a technical solution by means of which different designs of railway wheels can be inspected in short periods of time. In particular, inspection in drive-over operation should be possible, by means of which the inspection results for a complete train can be compiled during the period in which an associated inspection device is being driven over. Said aim is achieved in that the rolling railway wheelset passes through a spatially restricted magnetic field which is coupled in through the rails on which the associated rail vehicle is guided. For that purpose, a device is used, wherein an electromagnet (4; 5) is arranged between the rails (2; 3), on which electromagnet a measuring coil for registering changes in the magnetic flux is arranged.
