Apparatus is provided for obtaining the electrical deposition of a protective coating onto the surface of electrically conductive, magnetically-attractable metal articles. With the apparatus, a multitude of various articles, e.g., screws, clips, bolts, nails and the like, which may be in mixture, can be readily and efficiently coated in batch or continuous operation. The apparatus includes stationary magnet means in close proximity to a coating bath and having sufficient magnetic field strength to affect the location of coated parts in at least a zone of the coating bath. This stationary magnet means is together in assembly with rotatable, i.e., movable means, e.g., a drum member housing the magnet means. The rotatable means has a face element at least partly immersed in the bath. In rotation, this element provides for movement of articles within the bath while they are held under the influence of the magnetic field.
