FIELD: printing industry.
SUBSTANCE: invention relates to the field of printing industry. A magnetic plate comprises a sheet or a block from magnetised composite material, having multiple areas arranged along its surface. At the same time the first area on the specified surface is magnetised by exposure to magnetic field with the help of a magnetising matrix of certain shape, having an external surface in the form of an image, a logo or a symbol. Besides, the first area is magnetised so that it is shaped accordingly to the specified image, logo or symbol, and creates the first magnetic field with the specified direction, and the second area on the surface of the sheet or the block that surrounds the specified first area is either not magnetised or is magnetised differently compared to the first area, as a result there is contrast provided between the created or magnetic fields.
EFFECT: group of inventions makes it possible to simplify manufacturing of a magnet and to increase extent of flexibility in respect of the magnetic field created by the magnet.
