A conveyor for moving small ferrous items. An endless flexible belt is supported by one surface of a framework made of a nonmagnetic material. Parallel bars of magnetic material are secured to the framework opposite the belt-supporting surface. Permanent magnets are secured to the bars to provide a continuous magnetic field for attracting the items onto the belt. The belt is provided with parallel strips of high-permeability corresponding to the underlying magnetic bars. The strength of the magnetic flux passing through the items is thus increased.
