The invention relates to a device making it possible to transmit a motion to a permanent magnet body in the region of the force of its permanent magnetic field characterised in that it consists of a permanent magnet 1 fixed to a four-roller carriage 2 which moves over the rails 3. A balance mass 4 with a weight of 1/100 of the magnet-carriage force will be fixed onto one of the sides of the magnet-carriage, the latter will attract an iron block 6 whose weight equals the force of the magnetic field of the magnet-carriage at a distance of 0.5 mm 7. In this journey the iron block gains weight in accordance with the force of the magnetic field 14. At this moment the weight of the iron block is transmitted to the rollers of the carriage element 8 and in the initial location of the iron block a lever 12 which was held by the weight of the iron block prior to its displacement is freed. About half such a pulling weight 10 is sufficient to displace the magnet-carriage which is subject to the weight of the attracted iron block and to half the force of its magnetic field, from the position AB to the position A<1>B<1>. During this journey the magnet-carriage passes over the iron block of the same fixed size 11 in the vicinity of the point C, by which it is partially attracted. The attracted iron block will be outside the region of the force of the magnetic field and will fall in the initial location, onto the lever 12 whose other half is subject to the weight which is equal to that of the iron block 13. <IMAGE>
