Abstract

The invention discloses a physical experiment demonstration equipment for middle school education, which solves the problem of too long pause time caused by the replacement of the demonstration aluminum sheet. The lower end of the round tube is provided with a docking movable column, the upper end of the base is provided with a docking hole, the docking movable column penetrates the docking hole and is connected with the nut, the upper end of the round tube is connected with an assembled support frame, and the upper end of the assembled support frame is connected There is a connection structure, the connection structure is connected with a rotating seat, and the rotating seat includes a rotating head, a fixed pipe, a screw rod for the first demonstration of the connection of the aluminum sheet and a screw rod for the second demonstration of the connection of the aluminum sheet; a physical experiment for middle school education of the present invention Demonstration equipment, using a rotating seat to connect two demonstration aluminum pieces, can rotate the two demonstration aluminum pieces, and then facilitate the demonstration operation of the demonstration aluminum piece and the magnet for electromagnetic damping demonstration, improve demonstration efficiency, and save demonstration aluminum piece replacement time.

Description

technical field [0001] The invention relates to the field of physical experiment demonstration equipment, in particular to an electromagnetic damping demonstration device. Background technique [0002] Electromagnetic damping refers to the phenomenon that when a conductor moves in a magnetic field, the induced current will cause the conductor to be subjected to an Ampere force, and the direction of the Ampere force always hinders the movement of the conductor. The electromagnetic damping phenomenon originates from the principle of electromagnetic induction; [0003] The Chinese utility model patent number is: CN201320549119.5, and the patent name is electromagnetic damping demonstrator. The scheme adopted is: electromagnetic damping demonstrator, including bottom plate, vertical plate and magnet block. The bottom of vertical plate is connected with bottom plate and vertical plate by screws. The sides are connected with parallel aluminum tubes and organic tubes through conne...
