Abstract: Articles having axial leads, such as diodes, are handled by initially storing the articles within a magnetic bin and feeding the articles from the bin with a magnetic wheel. The articles are magnetic but they are not ''''magnetically symmetrical.'''' The magnetic asymmetry causes a tangling of the articles when they are suspended within the storage bin. A number of techniques are provided to eliminate the tangling: the field strength of the bin is reduced, the field is biased to one side of the bin and the bin walls are placed close together to constrain the articles. Additional improvements in handling are achieved by operating a magnetic feed wheel with discrete high angular-acceleration steps so that the articles which are not singularly attracted to pickup locations on the wheel are shaken free of the wheel by the stepping action. Thus, uniform feeding of the articles is achieved.
