An element which generates a magnetic field for fastening a compressor wheel to a turboshaft of an exhaust-gas turbocharger, has a basic body and a thread. In order to specify an element which generates a magnetic field for fastening a compressor wheel to a turboshaft, which element generates as high a magnetic field strength as possible and nevertheless can absorb without damage the forces and the tightening torques which occur during fastening of the compressor wheel to the turboshaft, the entire basic body includes a magnetic material and a sleeve is arranged in the basic body, which sleeve includes a non-magnetic material and has the thread which can be screwed to a mating thread of the turboshaft.
