A method for producing an electromagnet from a metal core and at least one metal wire is disclosed and may include joining a plurality of metal plates into the metal core by packing and winding at least one metal wire around the assembled metal core. Each metal plate may include plastically shaped areas and the plastically shaped areas of the metal plate may be connected by force-locking and/or form-fitting to the plastically shaped area of at least one adjacent metal plate in a joining direction. A multitude of windings may be wound around the metal core. The windings may be placed next to each other and/or on top of one another and a partial region of each winding may be oriented parallel to the joining direction. Furthermore, an electromagnet produced according to the method and a rotor of an electric machine having at least one electromagnet are disclosed.
