1. A device for braking a flow of molten metal in a device for continuous or semi-continuous casting of metals in a mold which is provided with opposite broad sides and opposite short sides, the device comprising:
two magnet cores facing a respective one of the short sides of the mold for generating a magnetic field and an induced current in a region of the molten metal adjacent to each respective short side, the cores being arranged such that the magnetic field generally has a direction perpendicular from the respective short side of the mold towards the center of the latter, wherein the mold is generally vertically arranged and at least one of the cores is arranged in or below a region wherein a flow of molten metal impinges the inner surface of an short side of the mold in a direction obliquely downwards; and
a winding comprising an electric conductor wound around each magnet core.
