DEVICE FOR DEMONSTRATION OF INFORMATION IN DYNAMIC MODE OF ITS PRESENTATION

摘要

The device for demonstration of information in dynamic mode of its presentation comprises electrical unidirectional pulse generator electrically connected with a coil of wire periodically interacting with magnetic field of argument pendulum. In immediate proximity from the coil of wire there is Hall transducer. The surface of a small size magnet argument pendulum is placed in parallel to the surface of the coil of wire and Hall transducer. The coil of wire magnet pole signs and specified magnet are chosen coincident. The coil of wire electromagnetic field strength value is selected maximum, in passing a small size magnet pendulum over the surface of the coil of wire and minimum – in removing the pendulum from the specified surface. The argument pendulum is made of a nonmagnetic material and rigidly fixed on the axis kinematically connected with a mobile area and a information object fixing device located from the side of the frontal surface of the opaque screen.
