A magnetic wedge for use in an electromagnetic device, arranged at the opening portion of a core slot for receiving a winding, comprising a magnetic member consisting of a group of magnetic strips arranged in non-contact from one another and at a predetermined inclination angle for the depth direction of the core slot, and a plastic member for molding said magnetic member. Such a construction of the wedge permits the magnetic property at the opening portion of a core slot to be improved.
