FIELD: locking devices. SUBSTANCE: padlock has following parts: shackle and cylindrical body with slot in which located are several strips slipped over long portion of shackle in following succession: first stationary strip made up of selection of permanent magnets, then stationary strip made of magnetopermeable material, further is stationary strip made of magnetopermeable material with cylindrical through holes, and finally stationary strip made of nonmagnetic material with holes of complex configuration which are coaxial with holes of preceding strip. Located in holes are locking rods and small cylinders. Control of location of locking rods is effected through slot in padlock body and also through holes in movable strip. EFFECT: high efficiency. 2 dwg
