Abstract

The invention discloses a buoyancy teaching demonstration device for a physical electromagnetic induction experiment, which comprises a base, a second baffle and a top plate, wherein the base is internally provided with a servo motor; the side edge of a first bevel gear is provided with a second bevel gear; a sleeve plate is installed on a second rotating shaft; the lower end of a limiting rod islocated in a limiting groove; the lower end surface of the top plate is fixed with a sleeving rod; the outer wall of a fifth rotating shaft is fixed with a full gear; the top of the top plate is provided with an annular through hole; and the top of a demonstration platform is provided with an electromagnet, a control switch and a battery from left to right in turn. According to the buoyancy teaching demonstration device for the physical electromagnetic induction experiment disclosed in the invention, the height of the demonstration platform can be adjusted according to the height of a teacher,the teacher is further ensured to do a demonstration experiment comfortably, the demonstration platform can rotate beside a student, the student can observe the experiment phenomena in a close range,and the student can better receive knowledge.

Description

technical field [0001] The invention relates to the technical field of physical experiments, in particular to a buoyancy teaching demonstration device for physical electromagnetic induction experiments. Background technique [0002] The physics experiment is to enable the theoretical knowledge in the textbook to be demonstrated through real objects, so that students can learn more intuitively, and at the same time can promote students' interest, and the conversion of magnetic force into buoyancy is an important experiment in physics. The existing magnetic force There are following problems in converting into buoyancy teaching demonstration device: [0003] 1. Most of the existing teaching demonstration devices converted from magnetic force into buoyancy cannot be adjusted in height, so that the height of the teaching demonstration device cannot be adjusted according to the height of the teacher, and the teacher cannot demonstrate the experiment at a comfortable height; [0...
