    The invention relates to magnetizing apparatus for the magnetization with coded orientation of magnetic blades (6) to be embedded into two sides of a magnetic key shank forming part of a magnetic safety lock system, wherein tapering flux-conducting soft iron shanks (2, 4) are coupled to the poles of an exciting magnet (1) of the apparatus. Between the shanks is an air gap (3) into which a feeding mechanism feeds the blades (6) to be magnetized. The magnet is a permanent magnet (1) made of intermetallic compounds of rare earth metals of shell 4f with transition metals of shell 3d by means of powder metallurgy or casting. The areas of the soft iron (2) which are contiguous to the air gap (3) are made of a material of high saturation value. The direction of the feed of magnetic blades (6) is parallel with the direction of the magnetic field (dipole) of the poles of the flux-conducting soft iron (2). The invention also includes apparatus for the total through-magnetization of the rotor discs of the lock-inserts of magnetic safety locks. In this variant, there are two symmetric magnetic cirucits, with permanent magnets (1, 1a) made of intermetallic compounds as above, with pairs of soft irons (2, 2a) and tapering shanks (4, 4a) facing one another across an air gap (14) and being of opposite polarity.

    The width of the i-shaped part 5 is chosen so that it corresponds to the width of the magnetizable magnetic plates.
    The magnetizing device (Fig. 5) serves to completely magnetize such rotating magnets, which are inserted into the magnetic inserts of the locks, as well as to obtain magnets of the type of anisotropic materials. The magnetizing device (Fig. 5) consists of two mutually symmetric magnetic systems, similar to that shown in Fig. 1. An air gap 10 is provided between the two magnetic conductors, receiving magnetizable rotating plates 11, which are located between the end faces of the tips facing each other. 3 and Over the opposite polarity. The flow direction of the magnetizable plates is parallel to the direction of the magnetic field.
    The tips 3 and 3 are fixed at the free ends of the magnetic circuit at an angle of about 120, the end surfaces 12 and 12a of the tips 3 and 3e are arranged parallel to the magnetizable plate 7 or 11, while the adjacent end surfaces of the free ends of the magnetic circuit are inclined

During the removal of the magnetized plate from the air gap and the insertion of the next plate to be magnetized into this gap, the ROM will short the poles of the excitation magnet. If the insertion plate is stationary in the air gap, then this control shunt is disconnected for a short time, the plate is magnetized. Then the yoke is closed again, the plate is removed from the gap, the next plate is inserted and the process is repeated regularly.
