Abstract

The two hemicylindrical parts of the ring-like concentrator meet on one side of the bore with an insulating layer between them and on the other side of the bore they are in electrical contact. A cut-out is provided at the electrical contact surfaces which divides the contact area into two portions, one portion close to and one portion remote from the workpiece. These portions are pref. coated with a corrosion resistant highly electrical conductive material and ensure that an induced current flows in the concentrator, which current applies an even magnetic force around the workpiece circumference.
