Problems solved by technology

[0004] However, in the existing buoyancy demonstration device, teachers or students need to manually adjust the weight of the float during the demonstration. When adjusting the density of the fluid, it is necessary to use a stirring rod or a stirring device, etc., resulting in fluid loss. It is also necessary to clean the stirring rod or Stirring device, etc., time-consuming and labor-intensive

Abstract

The invention discloses a floatage demonstration device for physics teaching, and belongs to the technical field of physical experiment instruments. The floatage demonstration device comprises a tank,a support frame, a cubic measuring drum, a floating drum, a connecting rod and four inverted-T-shaped indicating blocks. A squire opening is formed in each of four side walls of the measuring drum. The top of the measuring drum is connected with the top of the support frame fixedly. The floating drum is located in the tank. The top of the connecting rod is inserted into the measuring drum. The four indicating blocks correspond to the openings one by one. One indicating block corresponds to one side wall of the connecting rod. The inverted-T-shaped portion of each indicating block penetrates the corresponding opening to be fixedly connected with the corresponding side wall of the connecting rod. The other portion of each indicating block is located in the corresponding opening or outside the measuring drum. The floatage demonstration device has the advantages that the weight of the floating drum can be changed through an electromagnetic coil; a first magnet and a second magnet are arranged at the bottom of the tank, the second magnet drives the first magnet to move, and fluids in the tank can be stirred, so that density of the fluids is changed; the floatage demonstration device issimple to operate and has high efficiency.

Description

technical field [0001] The invention relates to the technical field of physical experiment instruments. More specifically, the present invention relates to a buoyancy demonstration device for physics teaching. Background technique [0002] Buoyancy refers to the difference (combined force) between the pressure of the fluid (liquid and gas) on each surface of an object in a fluid (including liquid and gas). Archimedes' law is an important principle of hydrostatics. It points out that an object immersed in a static fluid is subjected to a buoyant force equal to the weight of the fluid displaced by the object, and the direction is vertically upward and passes through the shape of the displaced fluid. Heart. [0003] In middle school physics course teaching, the understanding of the cause of buoyancy, the influencing factors of buoyancy, and Archimedes' law is the focus and difficulty of physics course. Therefore, when teachers explain, they generally use buoyancy experiments...
