In forming magnetic blocks, a first permanent magnet may be lowered to the bottom of an upwardly open vessel, the vessel may be already filled or may be then filled with liquid and, while forcefully maintaining the first permanent magnet in that position, further permanent magnets are gradually inserted into the vessel in a direction perpendicular to their resulting joint contact surfaces, where the adjacent surfaces of the superimposed permanent magnets have an opposite polarity, while during insertion of a further permanent magnet, the liquid is drained from the space in the vessel under that inserted magnet, whereby the motion speed of the inserted magnet is controlled as it bears down on the permanent magnet lying beneath it. The equipment for carrying out the method may comprise a vessel whose interior cross-section corresponds with clearance to the outline of the assembled permanent magnets, where sockets with regulating valves may be arranged along the height of the vessel, spaced so that their lower edges always lie above the upper surfaces of the assembled permanent magnets, and where all the parts are of non-magnetic material, while the bottom of the vessel may be furnished with a means for exerting an attractive force on the lowered permanent magnets.
