An assembly includes a container that contains a fluid composition having magnetic substances and a magnetization device that makes it possible to produce a pattern on a substrate onto which said composition has been deposited, the magnetization device including a holder and two magnets, at least one of which is in the form of a flexible sheet, the two magnets being at least partially superposed so that the field lines that they generate in combination with one another result from the interference between the field lines of each of the magnets.
